Common Causes of Toyota Highlander Tail Light Failures

The tail light is one of the most important safety equipment fitted in your car. Despite all the features and benefits it has to offer, unfortunately, it's not given equal treatment. No one wants a broken tail light because it requires much attention. The longer a broken tail light is put off, other's safety and yours will be at risk. In the following paragraphs are the most common problems encountered by tail lights.

Burned-out bulbs

Perhaps the most common problem and the easiest to resolve is a burned out bulb. The tail light assembly has many tail lights, each having their own function. Nevertheless, when a single bulb tail light stops working, the first thing to look for is a burned out bulb. Most tail lights can be accessed behind the assembly in the trunk of the vehicle. However, on some vehicles, the whole tail light assembly must be removed first to access the bulb. After removing the bulb, don't automatically consider replacement. It can still be inspected to determine if the filaments are broken, burned out, or the connection is loose. The tail light of one part is the same for everything in the assembly so you can swap some bulbs in the meantime before getting new ones.

Fried fuse

The next most possible and sensible cause of tail light failure is when the fuse of the tail lights get fried. This is the case when multiple lights fail all at once. You might be looking at a blown fuse after you diagnosis of the bulbs comes out negative. Locating the right fuse is a real squeeze so always consult the owner's manual. The fuse can be inspected by looking at the thin metal strip inside the fuse. See if it is broken or burnt.

Damaged wiring

The last thing to go wrong and the least to be expected to fail is the wiring that connects the tail light to the battery terminal. This is the final problem maker if neither the bulb nor fuse is blown. Under the same breath, loose wiring is attributed to a tail light failure most of the time. You can check the wiring and the connections to make sure they are in good shape and the surfaces are not corroded.

  • How to Keep Your Toyota Highlander Tail Lights in Top Working Condition

    The tail lights perform every time even with low maintenance. But this notion overshadows the fact that the tail light needs some attention from time to time. Many car owners and drivers disregard taking good care of their tail lights until it's too late. Therefore, doing some protective measures will guarantee that your tail lights will be in good shape until in the foreseeable future. Furthermore, this will definitely save you from hassle, expenses, and potential life-threatening scenarios. Here are some fast, easy and practical steps you can start incorporating to your maintenance routine starting today.


    Change burned-out bulbs as soon as possible.


    With proper care and use, bulbs in the tail light could potentially outlast your car. However, given the propensity of the material to burn out because of continuous use, changing the bulbs periodically will make certain that you won't be caught red-handed sporting malfunctioning tail lights by the authorities. Inspect the bulb, especially the filaments, to let you know how far or near are you from changing them.


    Check the fuse.


    The tail light is powered by electricity and like all things electrically-powered, a fuse is needed to regulate the power in the right doses. Without them, you risk burning the bulb or even worse, heightening the fire hazard of your vehicle. These parts wear out frequently, especially when they get stressed with continuous use. Once in awhile, it's worth checking the fuse intended for the tail light. In addition, you might want to clear out any debris that can get in between the fuse and the contact.


    Test the wires.


    This can be particularly helpful when you see the turn indicator light flash too fast, too slow, or even not at all, because they are all caused by a wiring problem. You've got a grounded wire to be exact. Test the wires directly by connecting a test light to the wire harnesses then check both the positive and negative terminals of the wire to identify wire is grounded.


    Clear the contacts.


    If the seal of the tail light assembly gets loose, the sockets will experience corrosion after prolonged exposure to moisture. You can clean them with an electric contact cleaner then reseal the assembly to keep moisture away.
