its quite simple actually.cheap ones give crappy results.
but it also depends on the intensity...like 6000k ones are white-ish sumtimes muddy like u mentioned.the 8000k ones are the clear ones.if im not mistaken.
I was on 2nd gear and in attempt to redline the FD. Suddenly upon touching redline, I heard either one or two electronic beeps from the car. Anyone knows what the beeps mean?
