After migrating from several VW Golf Plus with xenon, which had a top cornering (statically), ie with separate light bulb next to the xenon burner laterally irradiated (! So and not otherwise), I rose to a Golf Plus with Xenon order - but with "Cornering "the fog lights. You have to really write in quotes, it is my opinion no comparison to previous cornering. At the first trips in dark underground I got out to see if it's really up to - emotionally you can mE also a tea light next car ..... So resorted to the tried and tested Unlimited Night Breaker. One difference - apologies for the worn phrase - like night and day. I had only concern, but the very blue flask would look in the off state to blue in the spotlight, but is compatible to my taste. The first attempts were better than the original, but not so hot, but a few days after I was ordered remodeling a longer distance driving through thick fog. Must HB4 lights will only "run"? I know not by halogen, but now for the hour of continuous operation, they are as Fogger and (within the physical boundaries) really helpful as cornering. This time were the Night Breaker a direct hit.
