A tail light cover, also known as a tail light lens or tail light housing, is the transparent or translucent cover that protects the tail light assembly. It is typically made of plastic or glass and is designed to allow light from the tail light bulb to shine through while protecting the bulb from the elements. Replacing a tail light cover is a relatively simple task that can be completed in a few minutes with a few basic tools.
There are several reasons why you might need to replace a tail light cover. The cover may have become cracked or damaged, allowing moisture or dirt to enter the tail light assembly. This can cause the tail light to malfunction or to become less visible, which can be a safety hazard. Additionally, the cover may have become faded or discolored over time, which can make it less effective at transmitting light.
