OSRAMXENARC NIGHT BREAKER UNLIMITED D2S HID Xenon discharge bulb, discharge lamp, 66240XNB-HCB, duobox (2 units)

Pricey (all are). That’s said, a great bulb with good light colour. Bought for TT MK1 8n stock headlight, fit it in just a couple of minutes, with no issues. Didn’t do the pair, but it matched perfectly fine (dated but same bulb).

A clear difference in brightness. The whole beam area is consistent with no dark spots. Very much worth the cost. The colour temperature works well in damp/wet conditions. I find the more white/blue tint gets lost in those conditions. The difference between these and the night breakers isn't worth the £. These are the ones to go for. My car is a 2016 Mazda 3. I bought and returned a couple of cheaper bulbs and finally thought I'd spend some money. I'm so glad I did. I can now drive at night and see the road ahead.

So much brighter than the cheap bulbs from eBay

Hard to fault these. Bought these for an Audi A8 which was suffering one bulb going "pink", which meant it was on the way out. After doing a lot of shopping about and weighing up between OEM philips bulbs and non-OEM cheaper aftermarket ones, I opted for these. The main reason was that they were quite a bit cheaper than philips, but still a well known brand and promised extended beam etc. Also, changing bulbs on an A8 is a bit of a handling (either remove air fliter housing & move power steering pump or else take off wheel and remove wheel-liner to gain access!), so I weighed the extra cost against the hassle of having to replace them again if they went. Anyway I decided that the standard osram D2S was the best mix of cost and quality, then I saw the nightbreaker twin-pack for around £7 more than two standard ones, so I went for these. They came well packaged and looked to be good quality, as you'd expect from a German brand. They were definitely genuine, but after reading a few dodgy stories on forums I opted to buy from Amazon as a seller, so you would expect them to be genuine coming directly from Amazon. Anyway, fitting went well and they are both on my car now. I've only been out a few times at night in the city so far, but they are good, better than before I don't know. It'll take a late night out of town run to confirm that, but they do appear to throw light around the front of the car better and I no reason to expect they won't be good out in the real dark. As one other reviewer said already. They are a good obulb, but I wouldn't be "upgrading" to them unless I had to change a bulb anyway

Thank you

Whiteness good. Brighter then what was on car

Ok

Used as regular replacement in multiple vehicles. Good long life performace without coloured coating flaking off over time like on cheaper bulbs.
