Automotive Bulbs

Discover our comprehensive range of automotive bulbs, providing essential lighting solutions for all vehicle applications. Our selection includes high-performance halogen and Xenon headlight, spot, and fog bulbs in 12V and 24V options, some offering increased brightness for enhanced visibility. For signalling and auxiliary lighting, explore a wide array of stop, indicator, and tail light bulbs, available in various industry-standard cap types and designs to ensure optimal illumination and safety.

 

These references are industry-standard codes that precisely define a bulb's type, base, and electrical contacts, ensuring correct fitment and function. Here's a brief guide to what some common elements mean:

• 'H' series (e.g., H1, H4, H7): These typically denote specific Halogen headlight bulb types, indicating their filament configuration and intended application (e.g., H4 is a dual-filament bulb for both high and low beam in a single unit).
• 'P' series (e.g., P43t, PX26d, PK22S): These codes specify the bulb's base type, describing its physical shape, diameter, and pin arrangement, ensuring it locks correctly into the vehicle's socket.
• 'BA' series (e.g., BA15s, BAU15s, BAY15d): These refer to bayonet cap bulbs, commonly used for indicators, stop, and tail lights. The numbers (e.g., '15' or '9') indicate the base diameter in millimeters. Suffixes like 's' (Single Contact) or 'd' (Double Contact) denote the number of electrical contacts. Letters like 'U', 'Y', or 'Z' indicate specific pin offsets on the bayonet base, often for polarity or to prevent incorrect insertion.
• 'W' series (e.g., W2 x 4.6d, W2.1 x 9.5d): These are wedge base bulbs, where the glass base itself forms the electrical connection. The numbers refer to the base width and the maximum diameter of the glass envelope.
• 'SCC' and 'SBC': These explicitly state the contact configuration: Single Centre Contact or Single Bayonet Contact (more commonly Double Centre Contact), defining how power is supplied to the bulb.
