It's probably not a good idea to paint the reflectors that are around your low or high beam. I painted the bottom of the turning signal reflector and I like that look. I think it looks better than not painting it at all, but taping was a major, major bitch. It didn't come up perfect but if anyone ever gets close enough to look at them I'm probably in the process of running them over.
Of course the whole process was in vain because my lids are scratched beyond imagination.
