How To Change a Courtesy Light

Unfortunately many drivers learn that it's time to replace their tail light bulb when a Sheriff's Deputy pulls them over and tells them that the bulb has burned out. Typically this results in a "fix it" ticket but that means you not only have to get the light fixed but you have to spend more time out of your day going to the Sheriff's station to prove the repair was made.

The hard part of tail light maintenance is simply discovering that a bulb has burned out. Replacing a tail light bulb is a simple DIY project that can save you time and money (and tickets).

• Screwdriver
• Owner's manual
• Proper replacement bulb
• A Kleenex

When a tail light fails it's pretty obvious; the light simply doesn't come on. But is the light not coming on because the bulb simply burned out or is there another reason? If both tail lights fail at the same time it's probably a fuse and that will have to be replaced before you replace the bulbs.

Damaged lenses can also be a cause for bulb failure. A lens that is cracked can allow moisture in which in turn can short out the tail light bulb. If this is the case on your car you need to repair or replace the lens otherwise you are just inviting a new tail light to short out as well. When you're ready you buy a replacement you may want to consider buying two. If the bulb has burned out because it was near the end of its service life you can bet that the second tail light is going to go as well in the near future. You might as well change both now to prevent a second encounter with the police.

1. Determine how you can access the bulb. On some vehicles it will be by removing exterior screws that hold the lens in place. On others you will have to open the trunk and remove panels to get to the mounting screws.
2. Once access is gained, either push in on the burned out bulb and turn counterclockwise until it pops out or disconnect it from the wiring harness whichever is applicable. If your replacement bulb is halogen or xenon be sure not to touch the glass portion with your skin. These bulbs are specially treated to disperse the high temperatures that these bulbs give off and the oil from your skin can damage the coating causing the bulb to overheat and burn out. Using a Kleenex to hold the glass portion will not damage the special coating.
3. Install the replacement bulb using the reverse of the method used for pulling the burned out unit.
4. Reinstall the lens.
5. Once you have the bulb in and the lens mounted turn on the lights and make sure the bulb is working.

Changing a tail light is one of the simpler DIY projects but think about how much time and money you just saved by doing it yourself. Toss in the sense of accomplishment and you have another reason to learn more about how you can take care of your car yourself.
