Product Specifications

     The H3 halogen bulb is a common type of halogen bulb, widely used in the lighting systems of vehicles such as cars, motorcycles, and trucks—especially for fog lights, auxiliary lights, and headlights. Compared with other halogen bulbs, it features a unique structure and function, making it suitable for lighting needs that require higher luminous efficiency and a compact installation space.  

The 6V version of the H3 bulb is mainly used in older motorcycles, small electric vehicles, and early-model cars, whose electrical systems typically rely on a 6V battery. Additionally, some small agricultural vehicles, trucks, and electric tool vehicles may also adopt 6V electrical systems, thus using the 6V H3 bulb.

The 12V version of the H3 bulb is commonly applied in most modern vehicles, including contemporary cars, trucks, and motorcycles—particularly serving as headlights, fog lights, and auxiliary lights. Since the majority of electrical systems in modern cars and motorcycles use 12V voltage, the 12V H3 halogen bulb is more prevalent in the market.
