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

Modern Brilliance: Universal 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 many scooters and motorcycles, providing a crisp, 6000K diamond-white beam without the need for complex rewiring or bulky lighting systems.

Technical Performance Features

• True Plug-and-Play AC/DC Circuitry: Designed for both AC and DC 12V lighting systems, 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.

Comprehensive Fitment Guide

This H4/HS1 (P43T) base bulb is a direct replacement for any vehicle with AC or DC 12V lighting system, including the following models:

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.
