If you have a fogged or damaged tail light, you should remove the light and clean out any condensation. There may be a leak inside the light bulb, or a broken seal. A leak will prematurely wear out the light and cause the bulb to burn. The most common source of water leakage is the seal around the interior part of the tail light. To clean the tail light, you can use water to fill it with.
In addition to a dead bulb, a faulty bulb or fuse is a common cause of a failed tail light. While you might not be able to see the light without a flashlight, you can replace the light yourself with some basic tools. For example, you can replace a dead bulb with a new one, but you must be careful not to damage the filaments.
Before you can replace a fogged or damaged tail light, you must remove the battery. If you have an automatic transmission, you must disconnect the battery to replace the light. Once disconnected, you can remove the tail light housing and replace it. Remember to remove the light cover first, as it may cause the light to get fogged or damaged. If you don't know how to do this, you can consult a service manual to learn more.
