HB4 Bulbs
The HB4 headlight bulbs socket, also designated as 9006, represents a specialized socket type optimized for high-intensity single-filament high beam applications. HB4 bulbs are specifically designed for powerful, long-range high beam illumination used during highway driving and low-light conditions where maximum visibility is critical.
The HB4 socket employs a 9006 base type with a 3-prong connector, featuring a larger profile compared to some competing socket types to safely accommodate the higher-power electrical output characteristic of high beam bulbs. This robust design ensures secure and stable connections that maintain consistent performance even under demanding driving conditions.
Although H8, H9, and Hb4 share similar base designs and can physically fit into the same sockets, they are not directly interchangeable.
These bulbs are compatible with fog light bulbs, dipped beam bulbs and main beam 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
