OSRAM XENARC Night Breaker Laser D3S, 200% more brightness, HID xenon bulbs, discharge lamps, 66340XNL-HCB (twin)

These are incredible headlights, they are so bright and powerful although they are a bit pricey they are worth every penny. The install was for a 2016 Focus ST about 35 minutes of my time. Plug and play and super easy. My right bulb went out on my original factory set so I was researching between these and Osram CBI (Cool Blue Intense) although I like a blueish hue, I just didn’t want that for my car so I purchased these Osram Night Breaker Laser. They are incredibly helpful for night time driving and pure white color / tone which I wanted for my car.Shipping and delivery from this company was top notch, I didn’t want to wait so I opted for expedited shipping and it came 4 day’s earlier than the shipping estimated date. The best part is that the Osram include a two step verification, meaning you scan or enter the info from side label / QR code. Once you put in the right information it then asks you to march the pair of HID’s to the number on the website.Fantastic service, well worth the investment. Be sure to wear gloves when installing! Take your time and you won’t regret! I highly recommend this company and Osram!

These are slightly whiter than OE but still have a slight yellow hue once warmed up (but I wasn't looking for a color change from OE). brightness wise, I can't say they are that much brighter than the original philips OE bulbs they replaced for the extra premium for them. Overall great bulb. Can't tell longevity yet, just installed. OE was still running after 10 years but was getting dimmer and dimmer.

UPDATE: The headlights are pretty good I think, turns out the projectors in the CTS-V are absolute garbage, and it's not the fault of the bulb. Updating my review after finding out about that, these actually seem to be the best of the bulbs I've tried for my car.Bought these to replace the aging bulbs on my newly purchased CTS-V. Not only are they dimmer than the (mismatched) old bulbs that came with the car, their beam pattern means I get at most two car lengths of beam before they cut off and I can't see anything. The high beams seem somewhat decent, hence the two star review, but otherwise these are downright dangerous to use

These were installed in a 2015 Hyundai Sonata Limited Ultimate with about 195,000 miles. The original bulbs had gotten dim over the years. I really wanted to do LED, but LED is not interchangeable with HID when the housing was originally built for an HID Bulb. Honestly I have LED bulbs in my Ram and they are much brighter and cleaner, with a much sharper cutoff line, and would much prefer LED headlights, but these were the only real option I could find for an upgrade. They definitely are significant upgrade from the stock bulbs, not sure if I'd call it twice the light output, but it's noticeable and helpful. They are not easy to change in the Sonata, the whole light housing has to come out to do it, as there is a screw you have to remove to get the bulb out and a wire clip to align, but not horrible. May be easier or harder depending on the vehicle. Seemed a bit pricey for bulbs that dont blow me away with improved peformance, but HID bulbs are inherently pricey anyway. Overall given I had no other option I would do them again. But given the option, I would go LED all day long.

OEM headlights went out so I replaced them with an off brand, that was a mistake. They made it hard hard to see at night so I purchased these and I am so much happier with these headlights. Will definitely buy another set.

They are better than the original bulbs but not by much… Not worth the money imho

Came sealed and in perfect condition. Installed and they are bright, but I can’t say 200% brighter, but much better than the bulbs they replaced. Would have gone with cool blue boost if the shipping wasn’t a month away. If looking for a hyper white/hint of blue these are more 4500k

Installed on a 2018 Ford Focus ST3 with the adaptive bi-xenon headlights. Bulbs checked out as Genuine Osram products when I checked serial numbers on their website.These are much better than the stock OSRAM Original bulbs. Slightly less-warm color as well, I’d peg this at like 4800K (it’s a pure white, with a slight warm tint). Perfect for all-weather output, really cuts through rain and snow and fog very well. I never really need to turn on my fog lights anymore. Very happy with this upgrade.
