Why buy me?

The latest trend in the world of automotive lighting is LED. The Philips X-treme Ultinon P21W LED Retrofit is part of a new range of signalling and interior lighting LED bulbs. By choosing these bulbs by Philips, you know you’re getting the highest quality product on the market. Against halogen bulbs there’s no comparison: LED bulbs give off a much brighter intense light with greater longevity.

Please be aware that this range of X-treme Ultinon P21W LED Retrofit bulbs is designed for interior use. They can be used in an exterior application but it is not road legal to do and, in addition, due to technical differences between LED and halogen technology, a vehicle warning light may be triggered depending on the configuration of your vehicle. This is more likely to happen if your car was manufactured after 2005. We recommend purchasing the Philips CANbus warning canceller for LED lamps to solve this issue.
