does the stock R56 xenon not that bright? I'm puzzled that the xenon is dimmer than my other ride which also has a xenon headlight (reflector/projector). I asked around and they said R56 xenon not that bright. even the R56 halogen headlamp (non xenon unit) is brighter. For now I switched ON the bottom fog lamp just to assist the night driving. Seriously fog lamp (with the LED bulb) way brigther than the stock xenon. I have changed the xenon bulb to LED. So the LED is actually powered from the ballast and it is compatible. A bit brighter than before but still below par from standard xenon brightness
