Diode issue with H4 LED bulb
I've tried 2 sets of no name LEDs, but each time I notice a partial yellow cast/tint on the wall/vehicle in front of me.
And after looking at the bulbs up close, my hypothesis is that the cheaper bulbs have diodes that are, well, bigger than the area of the filament (halogen) and the yellow tint is actually reflected off the diode base.
Am I correct to say so? If not, is it just an issue of headlight leveling?
