If your tail lights aren’t working, it’s important to address the problem right away to get your car back in legal working order. There are several possible reasons why your tail lights aren’t functioning properly. Some issues are easily fixed while others will require a complete tail light replacement. However, this installment doesn’t have to be expensive if you find a reputable dealer offering used auto parts. Below are some reasons why your tail lights may fail.

Why Your Tail Lights Aren’t Working  

1. Blown Bulbs

A blown bulb is a very common cause of tail light failure. This usually occurs due to the length of time that the bulbs have been in use. LED bulbs can last for more than a decade, but all bulbs will eventually have to be replaced. Other causes of blown bulbs include leaving the lights on for long periods while not driving, as well as damage caused by excessive sun exposure or extreme temperatures. It’s always advisable to carry a spare bulb in your vehicle at all times.

2. Increased Electrical Problems

You can use a multimeter to measure the electrical current at the socket, and if no electricity is reaching it, you’ll find that the problem is likely an electrical error. A fuse blowout may also be responsible for the failure. If other possible causes have been ruled out, then you should contact a professional to examine the fuse box.

3. Low-Quality Bulbs

If you don’t know the full history of your car, it’s possible that low-quality tail light bulbs have been installed at some point during the car’s history. If you have already confirmed that the electrics in your car are working correctly, and the bulb is not old and hasn’t been exposed to extreme conditions, then it may simply be that your bulb has broken. You should locate the bulb and inspect the filament. It’s best to ask a professional for an inspection or contact a used auto parts dealer for replacement parts if the root issue can’t be targeted.
