OSRAM LEDriving Amber PY21W Interior Bulbs


OSRAM LEDriving Amber PY21W Indicator Bulbs (Twin)

Why buy me?

Choose OSRAM LEDriving Amber PY21W 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 are 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 would recommend that you purchase the OSRAM 21W CANbus warning canceller for LED lamps to solve this issue.

OSRAM LEDriving Amber PY21W Indicator Bulbs (Twin)

5Nice led bulbs!

Cool led blinker bulbs. Looking great on my car. especially at night it's noticable they are brighter than the original normal bulbs. You will still need resistors to prevent hyperflashing as these LEDs consume only 2 Watt each instead of the 21 Watt normal bulbs use. I advice to use a 10 Ohm/50 Watt resistor in parallel to each led. 4 resistors total on your car. Or you can switch out your blinker relay with a led blinker relay. Polarity doesn't matter with these bulbs so they will always work I will buy these again.

4Osram LEDriving Amber PY21

Got the pair to replace a lesser quality Chinese brand LED PY21 that had a failure in my front indicators. My impression of the OSRAM is that although the quality is excellent, it is somewhat dimmer than the other brand. It is however bright enough to function as intended. If you demand brighter, I'd go with the Phillip's Xtreme Amber led. I have them in my tails and they are plenty bright. For the price, you can't go wrong with the Osram though.
