I Read something, somewhere about how yo bring back the shine too old oxidized head light housing. I know replacing them is the best way too go but, money isn't growing from the trees here :-\
from what i read the best way is to wet sand them with a fine grit, then get even finer and finer grit. then use a plastic polish on them. i was going to do it, but i'm lazy, and then the deal came about with the smoke ones.
d_punch is right about the method but its really not worth doing... just save up for some new headlights :thumb:
