NULKOMMA E‑Bike LED Headlight with Horn — 4‑LED Waterproof 36V/48V, 15in Lead, Stainless Steel Mount

NULKOMMA's E-Bike LED Headlight with Horn is a compact, waterproof 4-LED front lamp with a 75–100 dB horn and a 3-pin male connector for 36V/48V electric bikes and e-scooters.

This replacement headlamp combines focused LED illumination and an integrated audible horn in a rugged ABS housing, designed for straightforward installation and reliable all-weather use. It connects via a waterproof 3-pin male plug and includes a stainless-steel mounting bracket that adjusts for angle, making it suitable for many electric bicycle and scooter models. The unit ships with a 15-inch lead and clear wiring instructions to reduce fitting time.

How bright is the light and what kind of beam does it produce?

The headlight uses four LED beads to create a broad, forward-facing beam intended to light the road and hazards in front of you during night rides. It balances spread and distance rather than acting as a long-range spotlight, which is ideal for urban streets, paths, and mixed-terrain trails.

• Four high-efficiency LED beads for even roadway coverage
• Designed to illuminate the rider’s path rather than long-distance searchlighting
• Brightness tuned for clarity at typical e-bike riding speeds

Will this fit my electric bike or e-scooter and how hard is installation?

The light is compatible with many 36V and 48V e-bikes and scooters that accept a 3-pin male waterproof connector; compatibility depends on wiring layout. Installation is fast and tool-free using the supplied stainless-steel bracket and hook attachments, with an adjustable tilt to aim the beam correctly.

• Waterproof 3-pin male connector for straightforward wiring
• Stainless-steel bracket and hook for quick, tool-free mounting
• Adjustable angle to align beam with your handlebar setup

Is the unit weatherproof and built to last outdoors?

The housing is molded from durable ABS plastic and engineered to resist water and everyday wear, allowing the headlamp to withstand rain, fog and light snow. The sealed connector and tough casing protect internal components from the elements, extending service life on regular rides.

• ABS plastic shell for impact and weather resistance
• Sealed 3-pin connector to prevent moisture ingress
• Designed for use on highways, wooded trails, and commuter routes

What if my bike uses a different wiring sequence?

Wiring arrangements vary between brands, and if the light doesn’t power up on first try, NULKOMMA offers wiring diagrams and support to help remap the connections. The seller can provide step-by-step guidance to change wire order so the lamp and horn function correctly.

• Contact support for wiring diagrams specific to your connector layout
• Simple rewiring instructions to match other manufacturer pinouts
• Customer assistance available if installation issues arise

Who is this for: Riders who want a dependable, multi-function front light—commuters, urban cyclists, and e-scooter owners seeking a compact replacement lamp with a built-in horn. It’s especially suited to users with 36V or 48V systems that accept a 3-pin waterproof connector and who prefer quick, tool-free mounting and weatherproof construction.
