C6 Corvette, 2005-2013 All models, D1S 5500K HID Bulbs, Low Beam: Osram Xenarc 66140 CBI, Pair

The Best: Easily the best D1S bulbs to ever hit the market, we are honored to offer the ultimate Osram CBI Bulbs. Indeed they are the "Rolls Royce" of D1S Lamps.
Amazing: What makes them so amazing? Osram's Cool Blue Intense bulbs offer more lumens than the once industry-standard Philips lamp, but with a higher Kelvin rating of up to 6000K. Whereas most bulbs lose lumens when their Kelvin rises, the CBI's still manage to give users the benefit of brighter light combined with whiter light - the best of both worlds indeed!
Backed: Bottom line? Everybody who uses them agrees they're among the best D1S bulbs ever made. We've never heard a customer complain that their Osram's weren't worth the money, and most of the guys here at TRS use them in our own vehicles. No matter the preference, we have your Osram HID replacement bulbs!
