XENARC COOL BLUE INTENSE D3S, +150% more brightness, up to 6,200K, xenon headlight lamp, LED look, duo box (2 lamps), 66340CBN-HCB

Replacing the bulbs on my 2017 Focus ST - these are a great replacement - the color is good (a touch more blue than stock) and I expect them to last 7 years like the originals

I made the mistake of buying cheap D3S HIDs a little over 3 years ago. Come to find out, they didn’t last like the original OEM ones that came with my car. Not only that, but they also weren’t bright at all. The OEM ones lasted about 6 years. Never again am I buying cheap HIDs. I did some thorough research and ended up deciding on these. They’re noticeably brighter, and they make it a joy to drive at night. For reference, I have a 2015 Challenger Scat Pack.

The headlights were delivered exactly as described. I could verify that they were genuine. Unfortunately, the installation on my Navigator required removing the entire front bumper, and the body shop wanted nearly a grand for the install. BUT, that let me discover how easy it was for the return to be processed! I would buy from the vendor again. 100%

Great product quality construction very bright big improvement from stock

Osram 66340CBN-HCB. No where near 6200K. They're probably around 5300K. Good bulbs, but not what I was looking for. I have 6000K LEDS around my entire vehicle and was looking for HIDs that match but unfortunately these don't. Pros: Quality headlights Bright OEM Plus Cons: Color temp. not accurate Doesn't come with lock rings. (Most don't)

Stock HIDs lasted 7-years. Bought these as replacements, and they look and work great.

I received a set of used bulbs, the package seal was broken and you can clearly see that the bulbs have been installed previously.. they are all Scratched up where they clip into the headlight..

Throughout the years, I've use many Osram and Phillips HID bulbs. These 66340CBN-HCB look NOWHERE near the photos used in the Amazon ads. I didn't want them to look like cheap "blue" bulbs but I want it to look more like OE LED lighting which is just a very cool and bright white. If you look at the photo of the three out-the-front lighting examples in the Amazon listing: https://m.media-amazon.com/images/I/61U9l02P93L._AC_SX679_.jpg ...the ACTUAL output looks like the middle photo (the "Original"). It looks NOTHING like the one on of the right (which I wouldn't want it to be that blue either). I was hoping for a mix (colorwise) of the left photo and the right photo and the brightness of the left photo. No Dice. These weren't much of a upgrade from the factory OE bulbs. Rather disappointed.

Aydınlatması çok iyi. 👍 İlk başta buz mavimsi oluyor daha sonra sarımsı bir beyazlığa dönüşüyor. Fakat ürün çok kaliteli.

Excelente calidad de iluminación y son originales, quedaron perfecto en mi automóvil

اضاءة ممتازة جداً و اكثر انتشار و وضوح

Type: HID Xenon headlight bulbs (D3S) Brightness: +150% more light vs standard xenon Colour Temp: Up to 6,200K – crisp white with LED-style blue tint Fitment: D3S socket – factory xenon setups (check compatibility) Use Case: Night driving, AV filming, festival runs, motorway missions 💥 Why They Deserve Big Compliments These bulbs are a proper upgrade for style and visibility. The 6,200K colour temperature gives you that clean, modern LED look—crisp white with a subtle blue edge, perfect for matching DRLs or giving your ride a premium finish. But it’s not just about looks: OSRAM claims up to 150% more brightness, and real-world users report noticeably better spread and clarity, especially on dry roads1 . The beam pattern is tight and uniform, reducing glare and improving contrast. Whether you're navigating dark country lanes or filming AV content at night, these bulbs deliver cockpit-grade clarity and confidence. ✅ Big Wins +150% brightness—serious upgrade over stock xenons 6,200K colour—clean white with LED-style tint ECE certified—road legal in UK and EU No coating—pure arc colour, better light transmission Long lifespan—OSRAM’s build quality holds up Amazon rating: 4.5 stars from 1,100+ reviews Tested against Night Breaker and Classic—holds its own in brightness and style ⚠️ Minor Trade-Offs Not ideal in wet weather—blue-white light reflects more glare Pricey—around £110–£180 per pair depending on seller No “night and day” difference—upgrade is noticeable but not dramatic Requires proper alignment—beam pattern depends on headlight housing Not compatible with halogen setups—D3S only 🧍‍♂️ Personal Verdict Used these in a factory xenon setup—beam was clean, colour was sharp, and visibility felt premium. For around £110–£180, it’s a proper bulb upgrade that adds style and cockpit-level confidence to your night drives. If you want that LED look without switching to full LED units, this one’s a winner.
