## Description

OSRAM XENARC NIGHT BREAKER LASER D4S, +200% more brightness, HID xenon bulb, discharge lamp, 66440XNL-HCB, duo box (2 lamps) : desertcart.co.uk: Automotive

Review: Completely changed my A6's lights - massive improvement. - tldr: superb bulbs in focus and light output. I had an old pair of ds3 in my a6 and swapped them for a new pair because they weren't lighting the road well enough. The result was nothing changed - they still seemed to be lighting the hedges better than the road.... so I started digging for tech tests on headlights. These always came up with one of 3 headlights - with this one being the most powerful - the others being more blue-ish light which are a cooler look but apparently do not cut through heavy weather as well. (another Osram and a Philips). I decided to stump up for these as they were consistently the most powerful legal bulbs on test. The effect was startling. The road is well lit and the beam pattern is much more focused. It has transformed the A6's headlights - that are notorious in the forums for being dim. Now I can see clearly and drive safely at night and in the wet. Pro: Superbly bright, reduced light scatter, good colour balance for bad weather. Cons: they ain't cheap. disclaimer.. I haven't tried the other two front runners, and to be honest I'm not going to. These are great as it is. Highly Recommended. Edit: I saw some others saying that they weren't 200% brighter than their old bulbs. They are only claiming to be 200% more than the standard bulb as tested when the rating was set. No bulb runs atthe intro rating anymore. They are about 25% brighter than most bulbs which is good. I think most of the difference is the way they focus the light.
Review: Honest review from a car guy! - Firstly, ignore the claims about them being 200% brighter (as this isn't compared to decent HID xenon bulb). But they are definitely brighter than the OEM Philips HID bulbs in my BMW. They also light the road further than the Philips did, I dont know by exactly how much but it was certainly noticable. They're never going to look like laser headlights because they're not! They do appear to be whiter (even if not the whitest!). One of my bulbs failed so I decided to go with these (and im happy I did) but ultimately if both your headlights are working and your somewhat happy with them then its probably not worth the price these things cost. In terms of longevity, I cant comment as they only been fitted a few days but I've used Osram in other cars I dont think I've ever had to replace them before selling the car and so I trust these will be the same. In short; better than most OEM bulbs, probably the brightest road legal HID bulbs you can buy and would recommend the product, maybe not the price!

### ⭐⭐⭐⭐⭐ Much Brighter then standard HID Bulbs
*by S***D on 10 August 2020*

I fitted the new bulbs just a day ago however I work shifts so finishing at 23:00 last night gave me a chance to really see how good the OSRAM HID Nighbreakers really are especially as a big chunk of my commute is 30 miles down the motorway. Well I was not disappointed, the distance that the light is thrown on to the road in front of you did not seam any different to the standard OSRAM HID bulbs I replaced, however, these are considerably brighter and whiter, and I did notice that the light did seam to be a lot better at illuminating the passenger side of the road, the hard shoulder did seam to be a lot better illuminated than before. The only real negative I can say is that even though I appear to have got the bulbs at a very good price they are still very expensive compared to the Standard OSRAM HID Xenox bulbs, of which I could have purchased for £40 less and to be fair, standard OSRAM HID Xenox bulbs are still very good.
