Choosing among electric bike headlight kits is less about picking the biggest feature list and more about matching a kit to your bike’s power system, connectors, and mounting points. I rank the D1 E‑Bike Light first for its broad 24V–72V compatibility and complete front-and-rear signaling, while the Zaisport kit is a clearer match for riders who want stated lumen output and a defined 24V, 36V, or 48V fit. The 12–48V Onature kit stands out for broader low-voltage compatibility and a horn, though it lacks a brake-light function.

The main tradeoffs are practical: the D1 offers the widest voltage range but may still need wiring adaptation; Zaisport specifies its power draw and connector but needs a 5W-capable light port; and the 36V/48V Onature kit combines signals with a horn but is explicitly not water resistant. I compare these kits by compatibility, safety functions, installation requirements, and weather suitability so you can rule out mismatches before choosing.
Key Takeaways
- The D1 covers 24V–72V and pairs a 4-LED headlight with a horn and a rear light offering brake and turn signals.
- Zaisport provides stated 400-lumen front and 100-lumen rear outputs, but its 5W minimum and XH2.54 connector need checking against your bike.
- The 36V/48V Onature kit includes an 80–100 dB horn and rack-mounted rear signals, but its lack of water resistance limits wet-weather suitability.
- The 12–48V Onature kit is the only option here that lists 12V compatibility and hazard mode, but its rear light does not include a brake-light function.
- Before buying any hardwired kit, confirm battery voltage, light-port output, connector type, and rear mounting measurements.

More Details on Our Top Picks
D1 E‑Bike Light 24V–72V Multi‑Switch Headlight and Taillight
I rank the D1 first because it combines a broad 24V–72V range with a genuinely complete set of road-facing functions: a 4-LED headlight, integrated horn, and rear light with running, brake, and turn-signal modes. That makes it the most balanced kit in this group for riders who want more than a front lamp. The stated range also spans more e-bike systems than the 36V/48V Onature kit or Zaisport’s 24V, 36V, and 48V compatibility.
Its advantage is not that every installation will be simple. The D1 is described as a plug-and-play kit with wiring and adapters, but the product information also warns that wiring may be needed for some bike models. I would treat the wide voltage range as a starting point, then verify the bike’s light-port connector and power output before ordering. That is particularly important when comparing it with Zaisport, which specifies a 5W minimum and an XH2.54 connector, or with the 12–48V Onature, which explicitly supports 12V.
The thumb-operated handlebar switch brings the controls within reach, and the rugged, water-resistant composite housing makes the D1 a more appealing choice for regular outdoor use than the non-water-resistant 36V/48V Onature kit. Its tradeoff is the switch itself: it can be fiddly to operate while riding. Buyers should also distinguish the D1’s multifunction rear lamp from the final Onature option, which has turn signals and hazard operation but no brake light. I would pick the D1 for broad system coverage and full rear signaling, while skipping it if the bike’s wiring is sealed, difficult to access, or not confirmed compatible.
Pros:- Broad stated 24V–72V compatibility
- 4-LED headlight and integrated horn
- Rear light includes running, brake, and turn-signal functions
- Water-resistant composite housing and included wiring adapters
Cons:- Some bike models may require wiring work
- Handlebar switch may be fiddly to operate while riding
- Specific lumen output and minimum light-port power are not stated
Best for: Riders who want a front light, horn, and rear running, brake, and turn-signal functions across a wide 24V–72V system range.
Not ideal for: Riders who need a confirmed direct fit for a proprietary connector or who want a particularly simple installation with no chance of wiring adaptation.
- Voltage range:24V–72V
- Headlight:4-LED light
- Rear-light functions:Running light, brake light, and turn signals
- Horn:Integrated
- Water resistance:Water resistant
- Mounting:Frame mount
- Housing materials:ABS, aluminum, and polycarbonate
- Included controls:Handlebar switch
Our verdict“I’d choose the D1 as the most balanced kit here when broad voltage compatibility and a rear brake light matter more than a guaranteed plug match.”
Zaisport E-Bike Light Kit with Turn Signals and Brake Light
Zaisport is the most straightforward choice for buyers who want the front and rear brightness stated rather than inferred from a description. Its 400-lumen headlight and 100-lumen taillight give a concrete basis for comparing output, and its rear unit combines turn signals with a brake light. Like the D1, it covers braking and turning at the back; unlike the D1, the supplied information spells out the lumen figures, cable lengths, and connector type.
Those details make the kit easier to check on paper, but they also expose the main fit questions. Zaisport supports 24V, 36V, and 48V systems and requires at least 5W from the light port. It uses a white male XH2.54 connector, so a bike with a different plug may need an adapter or wire splicing. I would verify both the power available at the lighting output and the connector before buying. A compatible battery voltage by itself is not enough to establish a direct electrical fit.
The 22mm handlebar switch and stated cable lengths offer useful installation details, and the rear light supports 50mm, 70mm, and 80mm rack spacing. Compared with the D1, Zaisport has less voltage breadth and no horn listed, but it provides more explicit output and fit information. Compared with the 36V/48V Onature kit, it is described as water resistant and includes the same broad rear functions without that model’s stated weather limitation. I would skip it if your light port falls below 5W or the connector is incompatible and you do not want to modify wiring.
Pros:- Stated 400-lumen headlight and 100-lumen taillight
- Rear light combines brake-light and turn-signal functions
- Lists cable lengths, XH2.54 connector, and rack-hole spacing
- Water-resistant and includes a 22mm handlebar switch
Cons:- Requires at least 5W from the e-bike light port
- Connector mismatch may require an adapter or wire splicing
- Listed voltage compatibility does not include 12V or systems above 48V
Best for: Riders with a 24V, 36V, or 48V bike who want stated lumen figures, rear brake and turn signals, and measurable cable and rack-fit details.
Not ideal for: Owners of low-output light ports, bikes with a different connector they cannot adapt, or riders who want a horn included.
- Voltage compatibility:24V, 36V, and 48V
- Headlight output:400 lumens; 4W
- Taillight output:100 lumens; 1.3W
- Power requirement:At least 5W
- Connector:White male XH2.54
- Rear-light functions:Turn signals and brake light
- Rack-hole spacing:50mm, 70mm, or 80mm
- Handlebar and cables:22mm switch; 1.5m headlight and switch cables, 1.7m taillight cable
- Water resistance:Water resistant
Our verdict“I’d choose Zaisport when its 5W requirement and connector match your bike and you value clearly stated output over a horn or wider voltage coverage.”
Onature 36V/48V E-Bike Light Kit with Headlight, Horn, and Turn-Signal Tail Light
This Onature kit makes a focused case for riders with a 36V or 48V e-bike who want a horn alongside front and rear lighting. The headlight is listed at 400 lumens, its horn at 80–100 dB, and the rear unit provides left and right turn signals plus a brake light. Compared with Zaisport, it adds a horn but offers fewer voltage choices and less installation detail about the electrical connector. Compared with the D1, its stated voltage range is narrower and its weather protection is a clear weakness.
The rear lamp is designed for a rack, with supported spacing of 50mm or 80mm. That will suit bikes with matching mounting points, but it makes fit checking more important than on a general frame-mounted arrangement. The system needs more than 5W from the light port, not merely a battery in the listed voltage range. The product details also warn that its connectors do not work with waterproof controllers or mid-drive motors. Those limitations are specific enough that I would check the bike’s manual or ask the manufacturer before attempting installation.
Weather exposure is the biggest reason I would place this below the D1 and Zaisport for general use: this kit is explicitly not water resistant. That matters for a bike left outdoors or ridden through rain, even if the horn-and-signal feature set looks complete. The final Onature kit is listed as water resistant and supports 12–48V, but it omits a brake-light function; this model includes one, yet gives up weather protection and broader compatibility. I would pick this one only when the rack, controller, voltage, and light-port output all match and the bike is used in conditions where its weather limitation is acceptable.
Pros:- Includes a 400-lumen headlight and an 80–100 dB horn
- Rear light includes brake and left/right turn-signal functions
- Rack fit is specified for 50mm or 80mm spacing
- Includes an e-bike switch and a one-year warranty
Cons:- Not water resistant
- Requires more than 5W from the light port
- Connectors are not compatible with waterproof controllers or mid-drive motors
Best for: Riders with a compatible 36V or 48V bike and rack who want a horn, brake light, and turn signals in one kit.
Not ideal for: Riders who commute in wet weather, have a waterproof controller or mid-drive motor, or cannot confirm a light port above 5W.
- Voltage:36V or 48V
- Headlight output:400 lumens
- Horn:80–100 dB
- Rear-light functions:Brake light and left/right turn signals
- Power requirement:More than 5W from the light port
- Rear mounting:Rack mount; 50mm or 80mm spacing
- Water resistance:Not water resistant
- Weight and material:0.2kg; plastic
- Warranty:1 year
Our verdict“I’d select this Onature kit only for a confirmed compatible 36V or 48V rack setup that needs a horn and brake light more than weather protection.”
E-Bike Turn Signal Light Kit with 400-Lumen Headlight, Rear Taillight, Handlebar Switch, and Horn
This Onature kit is the standout pick for riders whose system falls at the low end of the voltage range: it lists 12V–48V compatibility, while the D1 starts at 24V and the other two options are limited to 24V–48V or 36V/48V. It also includes a 400-lumen headlight, rear turn signals, a handlebar switch, and an 80–100 dB horn. Pressing both turn buttons activates hazard flashing, a distinct function not listed for the other kits.
Its broad voltage range does not make it a universal fit. The rear light is designed around 80mm rack holes, with a bracket for 50mm spacing, and the switch fits 22mm handlebars. I would measure the rack and handlebar before choosing it. The included cables, connectors, and mounting hardware help cover the physical installation, but buyers still need to verify their bike’s electrical connector and system requirements rather than assume a match from voltage alone.
The main compromise is the rear-light feature set: unlike the D1, Zaisport, and 36V/48V Onature kit, it has no brake-light function. That makes its signaling less complete if you want the rear lamp to indicate deceleration as well as turning. In exchange, this model is listed as water resistant and adds hazard mode; the 36V/48V Onature model has a brake light but is not water resistant. I would choose this one for a compatible 12V–48V bike where hazard flashing and a horn matter more than a rear brake signal, and skip it if the brake-light function is a priority.
Pros:- Listed for 12V–48V systems, the broadest lower-voltage coverage in this group
- Includes a 400-lumen headlight, rear turn signals, and an 80–100 dB horn
- Hazard flashing activates by pressing both turn buttons
- Water-resistant kit includes cables, connectors, and mounting hardware
Cons:- Rear light does not include a brake-light function
- Rack mounting depends on 80mm holes or the supplied 50mm bracket
- 22mm handlebar compatibility and connector fit still need checking
Best for: Riders with a compatible 12V–48V e-bike or scooter who want a horn, turn signals, hazard mode, and included mounting hardware.
Not ideal for: Riders who need a rear brake light, have an incompatible rack or handlebar size, or cannot confirm the kit’s wiring matches their vehicle.
- Voltage compatibility:12V–48V
- Headlight output:400 lumens
- Horn:80–100 dB
- Rear-light functions:Turn signals and hazard mode; no brake light
- Rear mounting:80mm rack holes; bracket for 50mm holes
- Handlebar fit:22mm
- Water resistance:Water resistant
- Mounting type:Fork mount
- Included components:Headlight, rear light, switch, cables, connectors, and mounting hardware
Our verdict“I’d choose this kit for a compatible 12V–48V setup that needs hazard mode, but not if a rear brake light is part of your must-have list.”
How We Picked
I ranked these products around the questions that matter when a rider is choosing an e-bike headlight kit, rather than treating every included component as an equal benefit. First, I looked at electrical compatibility: listed voltage range, required power, and whether the product description identifies a connector that buyers can compare with their bike’s wiring. A wide voltage claim is useful, but it does not guarantee that a particular light port or plug will match.
Next, I compared the safety functions. A bright front light helps the rider see and be seen, while a rear brake light, turn signals, and horn serve different purposes. I gave extra weight to kits that combine functions without hiding meaningful omissions: for example, one kit has hazard mode but no brake light, while another has braking and turn signals but narrower voltage support.
I also considered installation and fit. Included switches, cables, connectors, mounting hardware, handlebar diameter, and rack-hole spacing can determine whether a kit is a straightforward addition or a wiring project. Finally, I judged weather protection as part of suitability, not a minor spec. Product details supplied for these models are not equally complete, so I avoid treating an unspecified feature as a confirmed advantage. These rankings reflect the information available for the listed products, not hands-on testing.

Factors to Consider When Choosing Electric Bike Headlight Kits
I would start by checking the bike rather than choosing by the kit’s feature list. A headlight kit has to match the e-bike’s electrical output and physical mounting points, and those details can matter more than whether it includes another signal mode.Match voltage, power, and connector
Check the bike’s battery or system voltage, then confirm what the light port actually supplies. The D1 lists 24V–72V, Zaisport lists 24V, 36V, and 48V, and the two Onature kits cover 36V/48V and 12V–48V respectively. These ranges help narrow the field, but they do not prove that a kit will connect directly to every bike in that range.
Power requirements deserve a separate check. Zaisport needs at least 5W; the 36V/48V Onature kit specifies more than 5W. If your owner’s manual does not list light-port wattage, contact the bike maker before connecting a hardwired accessory. Also compare the supplied plug with the bike’s connector. Zaisport identifies a white male XH2.54 plug and warns that a mismatch may mean splicing. The other product descriptions do not provide the same connector detail, so ask for confirmation rather than assuming a plug will fit.
Decide which rear-light functions matter
These kits do not offer identical rear signaling. The D1, Zaisport, and 36V/48V Onature kit list brake lights and turn signals. The 12–48V Onature option lists turn signals and hazard mode but no brake-light function. A brake light communicates slowing down; turn signals communicate a planned direction change. A horn adds an audible warning, but it is not a substitute for either rear function.
If you want a horn, the D1 and both Onature kits include one; Zaisport does not list one. If hazards are a priority, only the 12–48V Onature description specifies that pressing both turn buttons activates hazard flashing. Choose around the functions you will use, and do not treat a longer list of controls as automatically better if a key signal is missing.
Check rack, frame, and handlebar fit
Mounting compatibility is easy to overlook when comparing lights by voltage. The D1 uses a frame mount, while the 36V/48V Onature model is designed for a rear rack with 50mm or 80mm spacing. Zaisport lists 50mm, 70mm, and 80mm rack-hole options. The 12–48V Onature kit uses an 80mm rear mounting pattern with a bracket for 50mm holes and a fork-mounted front light.
Measure the rear rack’s holes and check whether the mounting bracket leaves room for a fender or cargo. Zaisport and the 12–48V Onature kit list 22mm handlebar compatibility for their switches. If the bar is a different diameter or crowded with other controls, mounting the switch may be awkward even if the lights themselves fit. Cable length also matters: Zaisport publishes lengths, while not every kit provides the same level of detail.
Treat weather protection as a real tradeoff
For regular outdoor riding, check the stated water-resistance information rather than assuming an e-bike accessory is sealed. The D1 and Zaisport are described as water resistant, as is the 12–48V Onature kit. The 36V/48V Onature kit is explicitly not water resistant, which makes it a less suitable match for wet commutes or storage where rain exposure is likely.
Water resistance is not a promise that a unit can be submerged or that every connection is protected. Keep connectors properly seated, follow the maker’s installation directions, and ask about the intended exposure level if your riding regularly involves heavy rain. If the product description leaves weather protection unspecified, I would not treat that as confirmation of protection.
Balance convenience against wiring changes
A kit that includes a switch, cables, and mounting hardware may still need electrical adaptation. The D1 describes plug-and-play wiring and adapters but notes that some bikes may require wiring. Zaisport calls out connector mismatch and possible splicing. The 36V/48V Onature kit adds a specific warning about waterproof controllers and mid-drive motors. Those caveats carry more weight than a broad claim of compatibility.
Before installation, verify the bike’s wiring diagram and accessory-port limits, and use a qualified mechanic if the instructions do not clearly match your system. I would not cut or splice a bike’s wiring based only on a matching voltage label. A dependable fit starts with the light port, connector, and controller—not just the battery number.
Frequently Asked Questions
Can I choose a kit based only on my e-bike’s battery voltage?
No. Voltage compatibility is only one part of fit. Check the light port’s voltage and available wattage, the connector type, and the kit’s mounting requirements. For example, Zaisport lists a 5W minimum and an XH2.54 plug, while the 36V/48V Onature kit requires more than 5W and warns about certain controllers and mid-drive motors. If your bike’s documentation does not answer these questions, ask the manufacturer before connecting a kit.
Which of these kits include a rear brake light?
The D1, Zaisport, and 36V/48V Onature kit list a rear brake-light function. The 12–48V Onature kit lists rear turn signals and hazard mode but no brake light. If communicating that you are slowing is a priority, I would rule out the last option even though it has wider low-voltage coverage and a horn.
Which kit is listed for a 12V e-bike or scooter system?
The E-Bike Turn Signal Light Kit with the 400-lumen headlight and horn is listed for 12–48V systems. The D1 starts at 24V, Zaisport lists 24V, 36V, and 48V, and the other Onature model is specified for 36V or 48V. A 12V listing still does not confirm that the wiring connector and available power on your vehicle match, so check those before installation.
Which options have a horn, and how should I compare them?
The D1 includes an integrated horn, and both Onature kits list horns rated at 80–100 dB. Zaisport does not list a horn. The descriptions do not provide directly comparable horn specifications for the D1, so I would compare the feature as present or absent rather than assume equal sound output. Choose a horn-equipped kit if audible alerts matter, while checking local rules and the control layout on your bike.
Are these kits suitable for riding in rain?
The D1, Zaisport, and 12–48V Onature kit are described as water resistant. The 36V/48V Onature kit is explicitly not water resistant, so I would avoid it for regular wet-weather use. Water resistant does not mean waterproof or safe to submerge, and product descriptions do not all provide a protection rating. Check the maker’s guidance for rain exposure and make sure wiring connections are protected after installation.
Conclusion
For the most balanced setup, I would choose the D1 if your bike is within its 24V–72V range and you want a horn plus rear running, brake, and turn-signal functions. If you want stated lumen output and your bike meets the 5W requirement with a matching or adaptable connector, Zaisport offers the clearest installation and output details. For a 36V or 48V rack-mounted bike, the first Onature kit fits buyers who prioritize a horn and brake light, but its lack of water resistance and controller restrictions are significant limits.
Choose the 12–48V Onature kit if your system needs that broader voltage range or you specifically want hazard mode, and you can accept a rear light without a brake function. My final check before buying would be the light-port wattage, connector, rack or frame fit, and handlebar switch diameter. If any of those details remain uncertain, confirming them with the bike maker is a better step than relying on voltage compatibility alone.
