Our Review

Tired of the ‘fried egg’ look on your indicators? Then why not try OSRAM PY21W Diadem Styling Indicator Bulbs. The blue opalescent tinted 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 bulbs that you are currently using and replace them with the Diadems.
