Our Review

Tired of the ‘fried egg’ look on your indicators? Then why not try OSRAM Red Diadem PR21W Styling Indicator Bulbs. The coloured surface on these bulbs will make your vehicle stand out from the rest.

No changes or adaptations need to be made to your vehicle to use these bulbs, you just simply need to remove the existing Red Diadem PR21W bulbs that you are currently using and replace them with the Diadems.
