Night Breaker Unlimited halogen upgrade bulb from Osram provides as much as 110% more light on the road ahead, a light beam up to 40 metres longer and a 20% whiter light compared to a standard Osram halogen bulb. The difference is noticeable in the darker winter months where poor headlight quality and performance could affect safety and visibility. As a like-for-like replacement of a standard halogen headlight bulb, Night Breaker Unlimited is a very easy upgrade. No re-wiring is required, just simply remove the existing bulb and replace it with the corresponding Night Breaker Unlimited bulb.
