CBI: For years, the Osram Cool Blue Intense (CBI) was the gold standard for HID bulbs. Now, the CBI name is technically dropped for the "Next Gen" CBN. Long live the king, even with a name change!

The Best: Easily the best D2S headlight bulbs to ever hit the market, we are honored to offer the ultimate Osram CBI Bulbs. Indeed they are the "Rolls Royce" of D2S Lamps.

Amazing: What makes them so amazing? Osram's Xenarc 66240 CBI bulbs offer more lumens than the once industry-standard Philips 85122+ 4300K bulb, but with a higher Kelvin rating of up to 6000K. Whereas most bulbs lose lumens when their Kelvin rises, the Osram Xenarc 66240 CBIs 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 D2S headlight bulbs ever made. We've never heard a customer complain that their Osram Xenarc 66240 CBIs weren't worth the money, and most of the guys here at Headlight Revolution use them in our own vehicles. No matter the preference, we have your Osram HID replacement bulbs!

Genuine: Headlight Revolution is proud to offer these D2S headlight bulbs in their original retail packaging from Osram. We pride ourselves on being one of the last few distributors shipping genuine Philips & Osram lamps in the US. It is estimated that 80% of these D2S headlight bulbs sold through outlets such as eBay or Amazon are fakes.
