Easily the best D3S bulbs to ever hit the market, it's no wonder auto makers such as Mercedes and BMW are starting to spec the D3S CBI in their flagships models. Indeed they are the "Rolls Royce" of D3S Lamps.
What makes these so amazing? Osram's Cool Blue Intense bulbs offer more lumens than the once industry-standard Philips 85122 + 4300K bulb, but with a higher Kelvin rating of 5000K.
So what? Meaning they are physically brighter and offer more contrast at night, which makes them seem even brighter than they already are. In summary, everybody who uses them agrees they're the best D3S bulbs ever made.
Don't just take our word for it, read the reviews on HID planet!
We recommend professional installation especially with D3S bulbs, as their multi-pin connector is highly sensitive if installed improperly.
The K5 Optima Store & the Retrofit Source 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.
