H4 BIXENON Replacement Bulb - 6000K - 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 this lamp has an automatic switching function between low beam and high beam.

The xenon technology used in these lamps produces a very bright, crisp light that improves visibility during night driving. Bi-xenon H4-3 headlamps are designed to offer an easy transition between low and high beam so the light can be adjusted 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 headlamp 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 requiring a second bulb. This is achieved via a mechanical or electronic system that adjusts the position of the filament inside the bulb to deliver the desired beam.

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