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 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 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.

Color is an ABSOLUTE lie, NOT 6200K


I purchased these looking for the cool blue color and my lights were more of a 4300k stock halogen bulb color. If you want the original color your original OEMS were this is perfect but not what I was looking for.


Bright White Output!


These were arguably the best D2S bulbs you could get several years ago. Had ordered these for my 3rd gen Acura TL to replace the burnt out OEM ones. Fast forward to 2021 and I have installed these in some D2S retrofitted headlights on a new car and they are just like I remember! A GREAT performer for the new price. You don't need to drop $200 for the CBB ones unless you just NEED to have the best and brightest. These have like 80-90% of the output of the CBB but at like 50-60% of the price.


05 Acura RL


Recently the OEM hid bulb on the right side headlight would begin to Flicker or go out. So I came to The Retrofit Source and purchased these Osram CBI bulbs. The shipping was fast and the product is great. Will definitely be coming back to buy more once j begin my retrofit and upgrades headlight project.


05 Acura RL upgrade


Recently I became interested in retrofitting and upgrading my headlights. For the meantime I ended up buying these Osram CBI bulbs. These are definitely a upgrade compared to the OEM Acura bulbs, everything is much clearer and brighter then before


2007 Acura Rl


The output over my stock hid bulbs is by far the best. the price for the set isn't bad when compared to dealer price for one bulb. I would recommend these to anyone looking to replace or update their hid system


6 stars out of 5 !!


I ordered these bulbs and received them VERY fast. I replaced Phillips Ultinon 85122 so I was not expecting a huge change. I was dead wrong! These bulbs are bloody amazing! They cover a wider area on both sides of the car and shine farther, brighter, and stronger than the Phillips ! If you are using OEM bulbs, you're going to be blown away by these Osram CBI D2S bulbs ! The service at TRS is amazing, the quality is amazing, and these bulbs are amazing !


2014 Maxima


These bulbs are the best, from when the first fire up to when they are warmed up to their true color, you will not be disappointed with this quality bulb. I had some 6k's from diode dynamics but these truly blow those out of the water. Along with the morimoto fogs, the car looks phenomenal at night. Also shipping was very quick, got it in two days. I will definitely be back to buy more products from TRS.




Amazing. Absolutely amazing. Keep these great products coming. Love these lights. Nice and mint. These lights have revived the look of my TSX at night. I'm rolling around looking sexy. I highly recommend these lights. Buy a pair, heck buy a dozen of these.
