Choose OSRAM LEDriving Red P21/5W bulbs and benefit from perfect light distribution thanks to the modern diffuser material used. The bulbs deliver non-selective illumination thanks to homogenous light. 

These bulbs 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 would recommend that you purchase the OSRAM CANbus warning canceller for LED lamps to solve this issue.

Really intense reds but not as bright as I had expected!


I ordered a pair of these Osram P21/5W twins as my 19 year old Proton M21 Coupe needed brighter brake illumination. Unfortunately the horizontal bulb placement for the brake bulbs (instead of perpendicular) and the aged reflector in the tail light housing doesn't take full advantage of these LEDs. They do light with a fiery, deep red compared to the OEM P21/5W halogens and in the parking mode but glows only a tad brighter than the stock W5W parking halogens. I'm wondering if I should have ordered the more expensive Philips Ultinon P21/5W LEDs, despite the Philips advertising the wattage output as 1W, while Osram rates its P21/5W as 2.5W. The Philips Ultinon employs only two LED chips while this Osram uses a matrix of tiny red LEDs in a corn cob style housing. Since cars have uniquely designed brake light lenses, these Osrams might be brighter when fitted to a different car model compared to mine, so your mileage may vary. I might just buy the Philips Ultinon brake red LEDs in the future and see if they're brighter for my car's tail lamps. Right now, I'm pleased with the instant and uniformly lit illumination of these Osram P21/5W reds. They're actually a couple shades redder than my tail lamp's red lenses!
