I want yellow fog lights (I know they are better than white or blue), but everyone seems to be selling lights with either white or blue (rainbow) lenses. Blue light is useless for fog, but I can get yellow globes for the white lens lights, which would be fine. Has anyone tried fitting yellow globes to the blue or rainbow lens lights? I have seen a couple of blue lens projector lights and wonder if they would make good fog lights with yellow globes.
