H4 BIXENON Replacement Lamp - 12000K - H4-3

The H4-3 lamp is a common format used in many vehicles. The designation "H4" refers to the lamp classification according to the automotive lamp industry standard. The digit "3" in H4-3 indicates this lamp has an automatic switching function between low beam and high beam.

The xenon technology used in these lamps produces very bright, crisp light, improving visibility during night driving. H4-3 bi-xenon headlights are designed to provide easy transition between low and high beam, allowing the light to be adapted to varying driving conditions.

H4-3 bi-xenon lamps consist of a glass bulb containing high-pressure xenon gas and two electrodes. When an electric current is applied inside the bulb, a plasma discharge occurs in the xenon gas, producing intense light. This light is then reflected and focused through a series of lenses and reflectors inside the headlight unit to project a beam onto the road.

The distinctive feature of H4-3 bi-xenon lamps is their ability to switch between low and high beam without the need for a second bulb. This is achieved by a mechanical or electronic system that adjusts the filament position inside the bulb to provide the desired beam.

In summary, an H4-3 bi-xenon lamp is a headlight lighting solution that uses xenon gas technology to produce intense, well-focused light. Thanks to its switching function between low and high beam, it offers improved visibility and safety during night driving.
