Attention to CITROEN C3 2016, they do not work properly (they blink). Finally, they were installed in another car without any problem, PAJERO PININ 2006. In terms of lighting, don't think they are super bright. They are pleasantly powerful and the good thing is that the bulb is not visible through the light (the LEDs illuminate the mirror, not directly outside). In some cars (depending on the light), like AUDI A3 8L (and there it caused a malfunction), they illuminate the same as regular ones.

It is not intended for road use.
OSRAM has other bulbs for road use, even if neither these (nor any other LED bulb) have certification for road use.

Flawless stop lights. Both in intensity, color, and alternations. Don't waste money on cheap Chinese bulbs.
