A faulty tail light assembly on your Subaru Forester will not only cause hassle to you and your passengers, it can also increase the risk of tickets or even accidents on the road. Make sure that all the lights in your tail light assembly are working properly. Also, regularly check for damages that could be caused by hash weather conditions and harmful road debris such as rocks, pebbles, mud, or sticks. Here's how to spot problems in your Subaru Forester's tail light assembly and determine what causes them.
If you noticed that one of your tail lights has stopped working, immediately check the bulb. This problem could be caused by a burned out bulb with a broken filament. Examine your bulb first before buying a replacement bulb. If the bulbs don't appear to be burned out, then this failure could be caused by a problem in the ignition of your Subaru Forester.
If two or more lights in your tail light assembly have stopped working, check your fuse by looking at the thin metal strip inside it. This problem could be caused by a blown fuse. However, if your fuse isn't blown, you should also check your brake light switch. This switch is a small box-like object that is usually attached to the brake pedal arm. Use a circuit tester or test light to examine the brake light switch. Make sure that one of its two wires will be hot and the other one isn't when you depress the brake. If only one of the wires is hot, then that means your brake light switch is in good condition. If the problem still persists, another thing to check is your turn signal.
If the lights in your Subaru Forester's tail light assembly are still not working even if the bulbs and the fuse are in good condition, then it's time to check the wiring. Problems like this could also be the result of damages in the wiring. Make it a point to check all the connections and look for signs of corrosion in the internal surfaces. Also make sure that they are solid and properly connected as loose wiring could also be a possible culprit.
