Product Details

The Best: Easily the best D2S 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 Cool Blue Intense 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 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 D2S 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 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.

Trusted: For more than a decade, we've worked hard to earn our killer reputation. Car guys world-wide know that TRS carries the internet's best selection of high performance automotive and powersport lighting products at the best prices, and we've got the best, most knowledgeable team of real enthusiasts to help back it up. If we sell it, then you bet we've put it to the test on our own cars, trucks, and bikes. Need a recommendation on parts for your project? Got a tech question? Wholesale inquiry? Contact Us

Great Output...Color Way OFF.

Ronnie Jarrah Reviewed: 01.26.2018

These were definitely much more powerful than Philips White Vision Gen2, however the color I got out of them after 100 hours break in was no more than 4000 Kelvin. No white and definitely no blue...just yellow. I have pictures. If you are looking for output, these are solid, but if you want "Cool Blue", this is NOT it.

Infiniti M56s

Asim Khan Reviewed: 03.14.2017

These are definitely an upgrade from the stock 43k. They are pure white IMO and that is exactly what I was looking for. They match up perfectly with the Osram 6k Ledriving for the parking lights. Fast shipping and great customer service.

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.

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.

great bulbs

barna Reviewed: 05.25.2015

i was really skeptical about these bulbs. I didnt want to buy it cause of the price. Also i wanted the best performing bulbs for my rsx. I have ls460r projectors so why not put these cbi with them. WOW.. is all i can say. The money i spent on them was well worth it. I enjoy driving at night even more and they just look gorgeous shifting from blue, green, purple etc. Step up with these bulbs if your going to retrofit.

Replaced 5 yr old OEM bulbs

Justin Reviewed: 03.30.2015

I bought the Osram CBI bulbs to replace my 5 year old Koito bulbs in my Infiniti G37 sedan. The OEM bulbs seemed dull in comparison to other xenons on the road, so I figured I would buy the best I could get while maintaining a whiter look. TRS had amazingly fast shipping. I wasn't expecting them so fast but it was a nice surprise for a weekend install. After firing them up all I can say is wow! They throw light a little farther than the OEM, but it's not much. The biggest difference I notice is the brightness and the spread width of the bulb. It's much easier to see on the sides of the road than before. I can't compare to the XB35 since I have never owned them, but I can see why these bulbs are considered the best. Highly recommend these bulbs and buying it from TRS.

Beautiful White Light

David Reviewed: 03.05.2015

Awesome bulbs, with great white light. It gives a wider beam (don’t know how but it does) and lights up the road well.

The only issue I found was when it rains, the white light gets blended into the road and you can’t see that well.

Overall, beautiful bulbs with the FX-R retrofit.

CBI Blubs!!

ayran Reviewed: 08.14.2014

I've had the CBI's for 2yrs now. There the best bulbs, I've ever used point blank!! Ppl don't waste you're money on cheap knock off ebay, kits or fake bulbs. There bright af really good sharp cutoff! Looks like a disco ball jumping up and down with the flicker. Also biy the zkw-r clear Lens if you want the ultimate experience from these bulbs. There worth every penny, I'm very satisfied with the CBI.
