H4 headlight bulbs socket introduces a fundamentally new approach to headlight design by accommodating dual-filament bulbs that deliver both main beam bulbs and dipped beam bulbs functions from a single unit. This innovative setup removes the necessity for separate high and low beam bulbs, streamlining the headlight assembly while minimizing the number of components involved. The socket features a round base with a P43t type connector and includes three prongs for connections: ground, low beam power, and high beam power. This distinctive three-prong design sets it apart from single-filament socket types and facilitates the dual functionality that has made it a popular choice in many vehicle designs.

These H4 bulbs are compatible with main beam bulbs, dipped beam bulbs, and fog light bulbs for all vehicles. Are available in various brightness levels and colour temperatures, in halogen, LED, and xenon variants.

The straightforward plug-and-play design ensures hassle-free installation without requiring specialist tools or technical knowledge. Each twin pack provides a complete replacement set, as headlight bulbs should always be replaced in pairs to maintain balanced illumination and safety on the road
