The DRL's should dim when the parkers/lights are turned on. AFAIK it isn't illegal to have "driving" lights on at all as long as they are white bulbs. Yello and maybe green are illegal to have on unless it's raining/foggy as these are "fog" lights. I may be wrong, but I 90% sure

I am gonna try and work out an easy way to turn the DRl's into foggies and put HID's in perhaps
