H4 BIXENON Replacement Lamp - 5000K - 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 the H4-3 designation indicates that this lamp has an automatic switching function between low beam and high beam.

The xenon technology used in these lamps produces a very bright and crisp light, which improves visibility during night driving. H4-3 bi-xenon headlights are designed to offer an easy transition between low beam and high beam, allowing the light to be adjusted to different 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 of light onto the road.

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

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