This board was delivered today so out I went and plugged it into my car light OK, stop lights OK, four way flashers OK, indicators both flash together and not very brightly, put it on my Quad , indicators work but one rear light doesn't????? other ordinary bulb boards work OK with both vehicles, is this some kind of canbus fault with the lower wattage LEDs causing mayhem? Are there any electechy people to answer this one before I take it back.
