Our tail light lenses are made to protect the assembly's bulb. Due to the bulbs fragile nature, the tail light lens reduces the bulbs exposure to water, dirt, debris and other harmful contaminants that may cause the bulb to burn out or crack over time. Dorman's Tail Light Lenses are available in many different styles and colors, matching the overall aesthetic design of the original. Our direct-fit tail light lenses offer an exact fit, easy installation and ensures a proper fit every time.
