Universal HS1 / H4 LED Headlight Bulb - AC/DC Compatible
Description
This Universal HS1/H4 LED Headlight Bulb (SKU 0900-1128) upgrades your scooter headlight to crisp 6000K diamond-white output. Most LED bulbs need a steady DC battery supply, but this one has an integrated AC/DC rectifier circuit, making it a true plug-and-play swap on the fluctuating AC lighting circuits found on most scooters. There is no rewiring and no relay kit. Pull the old bulb, plug this one into the HS1/H4 (P43T) socket, and ride. Installation instructions are linked in the Manuals section of this listing.
Key Features
- AC/DC compatible: Integrated rectifier works on both AC stator and DC battery lighting systems.
- CSP LED chips: Brighter than a standard 35W halogen with a wider, deeper beam.
- 6000K diamond white: Cleaner, whiter light for better nighttime visibility.
- Aluminum heat sink body: CNC-machined housing draws heat away so the bulb runs cool and far outlasts a halogen.
- Plug-and-play: Standard HS1/H4 (P43T) base, no modifications required.

Installation Notes
If your headlight only turns on when the engine is running, your scooter uses an AC lighting system, and this bulb is a direct swap. At very low idle, you may notice a slight flicker as the stator pulses. This is normal for LEDs on AC circuits and disappears as soon as you give it throttle.
