Ricky Bobby, thanks for all the wonderful info, answered a lot of my questions. I'll be doing some research on it, see what I can find, and deciding what to do with my lights. I'll be waiting to see pics of yours.... Good luck...

If I buy new bulbs, where can I be guaranteed OEM bulbs? Ebay? BMW dealer?

High quality aftermarket Morimoto brand for 55 a pair

Or OEM Philips 85122 for 95 a pair, genuine too!

Mam, if you were prepared to buy new ballasts and use a 55w system....maybe consider the 35w osram 66240. They're expensive, but are as bright as you can go in regards to bulbs. Like RB stated, the biggest improvement would be from a projector swap though!
