Theres two ways to darken the front Head lights,One is to take them apart and paint the Insides,the other is to paint the outside with the Night shades Tint,with the night shades you can make the head lights look like a 06/07 model :~)
one of the members on here has an exchange going ,If you wanted to get the insides painted which is the route i'm Going when i get mine,he sends you a set of lights to use while he paints yours then sends yours back after hes done!
Hope this help later LF I'll try to find that Pic of the out side Tinted with night shades...
Found it :~) I like the out sides painted also...I feel they blend in with the Body more,Both ways looks good...

Reason I'm going with the inside painted ,Is i feel they will hold up better Long term than the out side being painted.
