Does anyone have any experience with the LED headlight bulbs that seem to be popping up these days? Im not talking about the LED DRL ala the R8 but the actual H1, H3 and H7 bulbs with LEDs instead of a filament. I have a 2000 A6 and plan to get the R8 style headlight units and was thinking it would be cool to have the LED low and high beams as well as the LED DRLs. If anyone has used them can you let me know what you thought of them?

Thanks
