I want the low down on headlights....
What do the "projector" headlights do for me?
I don't want to do any complicated wiring, I just want to install them and be done..

What is the difference between these 2 spyder products?
Pontiac Grand Prix 97-03 1PC Halo Projector Headlights - Chrome
and
Pontiac Grand Prix 97-03 1PC CCFL Projector Headlights - Chrome

What does each one do for me?
