Vauxhall Astra Festoon LED Bulb CANbus, 41mm Interior Light

Upgrade your Vauxhall Astra with a reliable, bright and CANbus-friendly lighting solution: the 41mm Festoon LED Bulbs (C5W/239). Each bulb features three Osram 3838 SMD LED chips, delivering a crisp xenon-white 6000K light that shines 360 degrees for even illumination. With a compact 41mm size and a 12-22V DC operating range, these bulbs are designed for seamless installation in number plate lights, interior map lights, glove boxes, boot lights, and other cabin fixtures. They’re built to combat common dimming, flickering, or electrical faults that can occur with cheaper LEDs, helping your vehicle look modern while staying road-legal and reliable.

These bulbs are cross-compatible with a wide range of vehicles (including Ford, Audi, BMW, Mercedes-Benz, VW, Opel, and more), and are specifically suited for European cars that require CANbus-aware lighting. The kit ships as a two-bulb pack, ready to replace the existing 239/272 festoon lamps and instantly boost visibility for both you and other drivers. The robust aluminium heatsink keeps performance steady, even in long drives or hot days, ensuring consistent brightness over many years of use.
