I would like to swap out my factory bulbs for PIAA Xtreme White PLUS Bulbs to match the H.I.D. on my 2007 X5. I have looked around for a good match, but other X5 owners were not that satisfied with their choice of HOEN and MTEC. These PIAA's are H11 Bulbs and they claim to use stock wattage of 55w but output 110W at 4000K. The downside is they are expensive. However, if they are worth it I will buy them. Can anyone shed some light or experiences with the PIAA bulbs? Thanks.
