Just put the GP Thunders in my new '11 this morning (also have them in the '10 M6 and was in the '10 750). I buy them from a guy here in CA, on eBay. $16.99/pair and free shipping. We keep about 2-3 packs on hand at all times. In my '10 750, the GP Thunders would burn out around 3000 miles!

Of course no where near as bright & awesome as factory LEDs, but SO much better than factory halogen H8 bulbs!
