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? The Osram Xenarc 66144 CBIs 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 Osram Xenarc 66144 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 the Osram Xenarc 66144 CBIs agree 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!
FEEDBACK: Don’t just take our word for it, read the reviews on HIDplanet!
GENUINE: The Retrofit Source is proud to offer these D1S 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 D1S bulbs sold through outlets such as eBay or Amazon are fakes.
