Universal HS1 / H4 LED Headlight Bulb - AC/DC Compatible

Upgrade your visibility and modernize your lighting with the Universal HS1 / H4 LED Headlight Bulb. Specifically engineered for scooters and motorcycles, this high-output bulb delivers a crisp, bright white light with significantly more lumens per volt than traditional incandescent or halogen bulbs.

The standout feature of this bulb is its integrated AC/DC circuitry. While most LEDs require a steady DC current, this bulb is designed to handle the fluctuating AC power systems found on many vintage and small-displacement scooters (like the Buddy 50 or Stella), making it a truly universal "plug-and-play" solution.
