Did you put in some different coloured light globes than the regular ones?
Like, I had a browse on the net for H4's, and there are different colours to choose from: yellow, white, blue, and ultraviolet:
H4 bulbs
I've got sealed beams at the moment, so I can't swap to brighter globes. I think I've got 50 watts for low beam and 75 watts for hight beem, or somewhere around there.
I might get the head light surround, then put brighter globes into that.
