D1S: Osram 66144 D1S CBI

  • $185.00
Tax included.

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 5000K. 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 DGM use them in our own vehicles.

Genuine: DropGearz Motorsports is proud to offer these 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 bulbs sold through outlets such as eBay or Amazon are fakes.
