I have an 07 A4 with the factory Bi-xenon headlamps. Was wondering what people thought of converting the DRL and fog lights to xenon, how much, and where are the best places to get them at a reasonable price??

 

I have Hoen xenon-match fogs (http://hoen-usa.com/) and chrome-covered xenon-match DRLs (search google for XC1156W).

The fogs look great. The DRLs are unfortunately not nearly as bright as the stock ones, probably cause of the chrome cover blocking half the light. But they match the mains!
