H4 BIXENON Replacement Lamp - 4300K - 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 number "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 very bright and clear light, improving visibility during night driving. Bi-xenon H4-3 headlights are designed to offer easy transition between low and high beam so you can adapt the light to different driving conditions.

Bi-xenon H4-3 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 bi-xenon H4-3 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 position of the filament inside the bulb to provide the desired beam.

In summary, a bi-xenon H4-3 lamp is a lighting solution for automotive headlights 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.
