you can buy a adhesive backed rock protector which colors and protects your lights. something like they sell here: https://rbaftermarket.com/catalog/i..._6389&osCsid=76cc56b8d05f5ca46df109fb839e27a6 http://www.rs25.com/forums/showthread.php?t=49104 otherwise you can use a semitransparent paint. such as "Night Shades". if you decide to paint make sure you do light even coats, and wet sand when your done.
If you want it PM me...I have a friend who has a shop in Blaine that specialize in Tinting taillights and headlights to whatever shade u want. I currently have my taillights tinted.
