LED Headlight Bulbs: Bases, Bezels, and Bikes
Choosing an LED headlight bulb is about two things: matching your stock bulb's base code, and confirming the corded fan and driver will clear the back of your housing. This guide decodes the base names (9005/HB3/H10, H11/H8/H9/H16JP, H7, H4 and more), explains why the right base does not always mean a clean fit, breaks down the fan-cooled design and real-output lumen specs, and covers the headlight bulb-out warning fix. Sold for off-road use.
