GTS, AVS, etc. Light Covers
Type: Rigid Plastic Cover
Plastic covers have been around forever and are by far the easiest to install. Generally they apply with Velcro or double sided tape to the lens. The problems with this are sometimes the fitment isn't the greatest, the details of the light don't carry over to the cover (e.g. this Mustang), and bugs and dirt can get trapped between the cover and the lens. One good quality though is they are removable if you just want the look for a car show or when parked.
