OSRAM XENARC NIGHT BREAKER LASER D3S, Next Generation, 220% more brightness, HID xenon bulb, 66340XNN-HCB, Duo Box (2 lamps), white

These bulbs are great I think they are a bit brighter than the original factory bulbs but not by 200 percent. Cheaper than dealer bulbs and have lasted for over a year since I’ve installed them and they are just as bright as new. Color looks great and overall great bulbs for chargers and challengers.

The original HID lamps in my now 7 year old car where beginning to be noticably dimmer, I knew it was time to replace them. I originally went with a budget brand 5500K lamp that *promised* to be "brighter and whiter than the 4300K OEM". Well, they got half of it right, kinda. They were slightly whiter than the originals but not a lot of difference. But brighter they most certainly were not, they were barely brighter than halogen bulbs, and had very uneven light with hot spots and dark notches.So I decided to bite the bullet and spend the money on these, as everything I read said they are the brightest HID lamps you can buy. And I'm not disappointed. They have the broad smooth even spread of light that the OEM lamps had, and are noticably brighter. Most definitely worth the premium price tag.Lesson learned. You get what you pay for.

Plug and play for my Volvo XC, looks great. Been over a year now and still going strongPlease buy proper lights for your car and don't put LEDs in non LED housings

‘14 Jaguar Ftype, nice replacement for OEM. Wouldn’t say twice as bright but certainly as good if not better than the original which were Philips XenEcoStart.Would recommend verifying its only a bulb by swapping your remaining good bulb to opposite side to make sure the ballast is not the problem.These bulbs have a code where you can go on Osram’s website and verify they are not knock-offs and mine were indeed authentic. Adequately packaged.F-type specific instructions- remove the headlamps from the car, it would be painful to try to replace with them in place and risk damaging the bulb as you try to get it back in. Undo headlamp electrical connection, Loosen the bumper fascia by removing four bolts holding it in place (two in the wheel well, two on the edge under the hood) to reveal one of the three bolts holding the headlamp in place, lift and rotate the assembly laterally to remove, remove rubber dust cover, push on the silver clasp to remove the braided cable to the bulb, there are two black plastic wings that rotate to release the bulb which then wiggles straight out, some of the metal prongs holding the lamp in place may appear bent but they are not, make sure the new bulb engages all the way into the prongs before twisting the black ring back in place. Check panel gaps before securing all bolts , do not over tighten as all connections are plastic tabs.Can’t speak to longevity as just replaced.

Bought this lights on Feb 2023. And waited for a whole week before i received the order. Seller said they don’t have the whole pack that come with 2 bulbs so instead they give me 2 single one. Too expensive for me and not that bright at all. Very disappointed.

Installed these because one of my 2014 Jeep Cherokee LED headlight bulbs went out and the other just seemed dim in comparison to the headlights on new cars. Jeep installed these for me, and what a huge improvement! Its literally like driving around with brighter brights as normal lights. No one flashes at me for too bright of lights. Visibility is fantastic. I also installed new LED fog lights to match the color of these. Equally a huge improvement over OEM and the color matching is near perfect! Installation I recommend a dealer do it, you have to remove the front bumper. Just replace all the bulbs and enjoy several more years of working lights, hopefully. I also replaced my interior lights with bright LED bulbs and upgrade the side door lights for when you walk up to the car. I have raccoons that hide out everywhere, don't like wondering whats under the car. Only thing I have remaining, is I want to somehow add a brighter backup light. Our driveway is dark. But these Xenarc Night Breakers D3S are just awesome!!!

I replaced my old standard Philips bulbs. I’ve used the previous generation of this bulb in my last vehicle and was super impressed. It’s bright, does the job but I wouldn’t say it’s noticeably 220% brighter. It also appears to be worse than the Philips for high-beam somehow. So, a fine bulb but I’m not sure it’s worth the hefty price tag.

I have a 2017 GMC acadia. After 7 years the passenger side bulb started to flicker. I did some research and while these were the most expensive lights, they got the best reviews in my research I read online and now I see why. Dramatic increase of light and so worth the money.
