WOW....You are lucky! Our Weisslicht LEDs for the Corona Rings arrived yesterday from Bimmian. We ordered a set for the "11 35d and our '10 M6. SAME bulbs, same part #...yet Bimmian charged $5 more for the M6!

BOTH in the 35d and the M6.....ERROR codes!! You think they are bright? We thought they looked dim, muted, too bluish and just really bad! Even if they had no Error codes, the GP Thunders are much brighter, crisper and look better...lights on or off.

OK, so I have decided to STOP trying to get a better Corona Ring. NOTHING is going to look the like factory LED rings the new 5 Series and 3 Coupe have. NOTHING. GP Thunders are the best compromise. They are just a direct bulb replacement, they are not yellow at all, they are very inexpensive...

So disappointed with Bimmian and these crappy LEDs. Funny, how you love them, and I hate them!! These just stink of cheap, Chinese Sh*t. Dressing them up with a German name and selling them in a cool, high quality box in the colours of the German National Flag...does not make a great product. Slimy and deceptive marketing at it's best!!!
