OSRAMXenarc Cool Blue Boost D3S Xenon Car Headlight Bulbs (Twin) 66340CBB-HCB

Definitely beats the eBay special. I have these installed in my Audi A4 B8 my headlights still move, the brightness is amazing, the highbeams are out of control, from a stop sign if I flip in my highbeams I can see 3 stop signs down now. FINALLY!!! I complained about the price at first but now I don’t think I’d install any other bulb. The coloring isn’t as blue as I thought it’d be but honestly I don’t care bc I can see the road and I live on Long Island and I can now see potholes at night. FINALL!!!

Item arrived perfectly and I’m very pleased with this order.

I purchased these lights for my 2014 Ford F-150, with HID projector headlights. They arrived from the seller on time and they were authentic Osram's 66340 CBB's (unopened and verification sticker in tact). Originally, I was going to replace my HID's with OEM 66340HBI's, but I had seen some positive reviews online about the CBB's, so I took a chance. My primary concern was the 7K rating. I did not want the lights to look dark blue, or even worse, violet in appearance. I just wanted a more updated look over the originals (HBI's only have an up to 43K rating). The CBB's offer a slightly stronger and cleaner projection appearance on the roadway, than my old HBI's. In my opinion, their rating of 7K is really more like a 5K and I think they were worth it over the OEM's.

Arrived broken.

First off The ones I received are authentic. Osram has a 2 step authenticity check you can do once you get the bulbs. you do not need to open the package to do this check.Lincoln MKS is the vehicle replacing OEM bulbsThis is what they look like to me.My Lincoln with OEM bulbs compared to a vehicle with traditional headlights.Lincoln appears white and the other is yellowish. Lincoln is 2X brighter then the other.Before I did anything with the bulbs. I sanded the headlamp lenses with 1500, 2000, and 3000 git emry cloth. then i used barkeepers friend made into a paste to polish them some more. then out came the rouge wheel. when I was done the vehicle didn't even look like it had any lenses over the headlights. Unfortunately because no manufacturer has seem to figure out a way to stop the plastic lenses from getting the micro cracks from the heat and UV of the bulbs. I do have this and it is seen when the headlights are turned on.I installed one bulb so I could do a side by side comparison so apples to apples if you get my meaning.These bulbs compared to the OEM is pretty damned close to what the OEM HID to "Legacy" is likeNot 2X brighter maybe 40% brighter.And they have the slightest blue to them. I would peg these things at maybe 6100K or so. Not the 7000 marked on the package. I had done some research and saw some people mention this. o it was something I was expecting.I also bought a set of Morimoto H11 55Watt HID's to replace the legacy yellow colored fog lights. They are 6500K so they should go well with these bulbs.Hopefully this should help me see better when "that guy" comes from the other direction."That guy" is the person with the pickup truck that has an HID conversion and didn't adjust the headlights so they are pointing at the ground more.I will post a photo a little later that shows the difference between Legacy, OEM HID and these bulbs.

As soon as I got these, I ran the part numbers through Osram’s Trust Program. I was thrilled that they passed with flying colors. They’re super easy to install when you have easy access to the bulb housing. Unfortunately, Audi made it super complicated so I had to partially remove the bumper and pull out the entire headlight. Once removed, it literally took a minute or two to replace them. That’s all on Audi so I won’t dock any points from Osram.Now on to the the bulbs. Wow, they’re super bright and much clearer and whiter than my stock Phillips 4300K xenon bulbs. They yellowishness is for the most part gone and they’re clearly a sharp white. I’ve only had them on for about 3-4 hours, but the difference is definitely noticeable. It’s like going to xenon for the first time from halogen bulbs. I have to agree with most of the previous reviews - these are closer to 5500-6000k and far, thank god, from 7000k. I wanted bright white and I got it.Like my stock bulbs, these aren’t the greatest in the rain. I’ve read that others had better rain vision with stock xenon’s but mine sucked. They were great otherwise. So I won’t dock any points for the rain performance.So yeah, I love these bulbs and they’re amazing an upgrade if your coming from the stock xenon bulbs. Don’t worry, they only have a tiny hint of blue and won’t look “ricer” at all. I’ll post an update, with pics, after some extended night driving in dry conditions.

These lights are for sure an upgrade over the F150 OEM 4.3k that comes stock. As what other reviews state, they aren’t 7k once warmed up. They are more of a 5.5k which is a pure white. Aesthetically, they look awesome on the road. The light output is about on par with stock, maybe slightly better.Anyone of is doing this to a 13-14 F150 HID-equipped, the two little bolts holding the HIDs in are a T9. Make sure your tool is magnetic!! They easily fall out into the headlight housing.
