Hi, i used Night Shades on my tails (as per my Avatar - it used to be a chrome look). cost me $20 from Super Cheap. I wouldnt do the heads for obvious reasons (i've seen cars with tinted heads - just dont think its a good idea for night driving). If u want the heads tinted, then get a pair of headlight covers for your car and tint them instead so u can use it during the day and take it off at night.
