Here is already enough been described what the burner all can, more light than the original 66140 Xenarc all. I got myself the NB and installed himself in the F11 BMW, Light switch to 0, ignition key and put away, then fidgets also nix. Light is very very yellowish halogen and from the light color. Not seen necessarily as Xenon. And me personally, it is also not bright enough, probably even if here rather the contrast the test brings the points. In fact, the light is not even so homogeneous, there are bright and dark spots. Property me then still the CoolBlueIntense fetched and fit I really better. Beautiful white light and reflects everything nice. Perhaps less coverage on the road, but in front of car subjectively brighter, VSL in rain and snow. bisserl strenuous, but that I can from. Conclusion: If good light with great contrast and more relaxation Will, who is reasonably buy the Night Breaker. If you like really white xenon light, which has actually only the CBI take because the NB must be harmless from the styling. I hope I have some help you with your decision.
