Our kits are precision computer pre-cut and are made with a high performance translucent softened PVC film with UV-stabilizers & gloss surface with adhesive backing. The material are applied in a manner similar to vinyl stickers/graphics. It will enhance the appearance of your vehicle, and will not crack, yellow, shrink or peel over time. This kit is design to be permanent, but can be remove at anytime without damaging your lights. This film is made to withstand any weather condition, high speed, debris, and pressured car washes. When comparing to taking your lights apart and painting the inside which will lead to uneven color, the old fashioned clip-on/double side tape that are easily stolen, and is much more troublesome and permanent. The static cling style, with moisture, will crack and eventually fall off. This is a much better alternative. It is a simple and easy method without having to spend hundreds on modification. Install the pre-cut overlays over the exterior of the light. The light does NOT need to be removed in order to install this. Installation instructions are included.
