Universal HS1 / H4 LED Bulb: AC/DC Compatible
Description
Modern Brilliance: Universal AC/DC HS1 / H4 LED Bulb
Drag your scooter’s lighting into the 21st century with the Universal HS1 / H4 LED Headlight Bulb. While most LED upgrades require a stable DC battery connection, this high-output bulb features an integrated AC/DC rectifier circuit. This allows it to function perfectly on the fluctuating AC power systems found on most 50cc and vintage scooters, providing a crisp, 6000K diamond-white beam without the need for complex rewiring.
Technical Performance Features
- True Plug-and-Play AC/DC Circuitry: Designed specifically for scooters like the Buddy 50 and Stella, this bulb handles the pulsing AC power from your stator as easily as a steady DC battery current.
- High-Efficiency CSP LED Chips: Delivers significantly higher lumen output than a standard 35W halogen, throwing a wider and deeper beam for safer nighttime navigation.
- Reduced Electrical Load: Draws only 35W of power, freeing up valuable wattage for your charging system and reducing heat buildup inside small plastic headlight housings.
- Aviation-Grade Heat Dissipation: The CNC-machined aluminum body acts as a massive heat sink, ensuring the LED chips stay cool for a lifespan that outlasts traditional bulbs 10-to-1.

Mechanic's Note: If your scooter's headlight only turns on when the engine is running, you have an **AC system**. Because this bulb is AC-compatible, it is a direct swap for you! Note that at a very low idle, you may see a slight "flicker" as the stator pulses; this is normal for LED technology on AC circuits and will disappear as soon as you give it gas.
