Upgrade your scooter's headlight to crisp 6000K diamond-white LED output with this Universal HS1/H4 LED Headlight Bulb. Unlike most LED upgrades that require a stable DC battery connection, this bulb features an integrated AC/DC rectifier circuit — making it a true plug-and-play swap for the fluctuating AC power systems found on most scooters. No rewiring, no relay kits, no hassle. Just pull the old bulb, plug this one in, and ride into the light.
Key Features
- AC/DC compatible — integrated rectifier circuit works on both AC stator and DC battery systems
- CSP LED chips — higher lumen output than a standard 35W halogen, wider and deeper beam
- 6000K diamond-white color temperature for improved nighttime visibility
- CNC-machined aluminum body acts as a heat sink — runs cool, outlasts halogens significantly
- Reduced electrical load — 35W draw frees up wattage for your charging system
- True plug-and-play — H4/HS1 (P43T) base, no modifications required
- Base Type: HS1 / H4 (P43T)
- Voltage: 12V AC or DC
- Wattage: 35W
- Color Temperature: 6000K (Bright White)
- Base Diameter: 43mm
- SKU: 0900-1128 | MPN: BA20D

AC system tip: If your headlight only turns on when the engine is running, you have an AC system — this bulb is a direct swap. At very low idle you may notice a slight flicker as the stator pulses; this is normal for LED on AC circuits and disappears as soon as you give it throttle.
