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. Our film also carries a 7 year warranty. 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. 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 remove in order to install this. Installation instructions are included. We also have a detailed install guide and video guide online.
