My 5000k xenon was becoming weaker - especially on wet road there were problems with the illumination. Although they looked "cool" - but I have the light in the car, so I can see something - and not so that the truck looks cool. So installed the Xenarc Night Breaker Unlimited: "Oh that's yellow." (Clearly I had already read ...). No matter - a first test drive showed a huge difference to the old burners in the coverage and in the range. Three days later, the first rain ride - there came the wow factor: The burners are precisely because of their color temperature right on wet roads. Brilliant. Heller are for me - purely subjective - only vehicles with LED light - All other lamps provides these burners (in the truest sense of the word) in the shade.
