Toyota Tundra Tail Lights

Common Issues with Toyota Tundra Tail Lights

Just like the other automotive lights on your pickup, the tail lights of your Toyota Tundra should be kept in good condition to prevent road accidents. And just like the other lights, they will soon wear out through constant use. When you already notice that the tail lights of your truck are not functioning properly, it is time for you to do some troubleshooting. Here are some of the usual problems you could experience:

The parking brake lights stay on.

There are several causes why the parking brake lights of your pickup stay on. The first one is the low brake-fluid level in the reservoir. The parking brake light serves as a low brake fluid warning, so this is a possible culprit why the light remains on. However, if the fluid level is at maximum, then another cause of the problem could be the tail light switch. Foreign objects may have blocked the switch which cause it to malfunction, or the switch itself has become faulty. You should diagnose the switch and the connecting wires to find the problem.

When the headlights are on, the brake lights don't work.

A possible reason for this problem is the wiring of the tail lights. You should check the supply voltage of the tail lights and stop lights because they are wired together. You should also look for signs of corrosion on the wires. It is important that you have the correct wiring diagram of your vehicle to see if the wiring of the headlights is connected with the tail lights beacause the headlight may have a different problem.

The tail light dims when the brake pedal is used.

If you have recently replaced the tail light bulb of your truck, then the new bulb can be the possible culprit. You can try to put the old bulb back, if it still has power left in it, to see if it still dims when you step on the brake pedal. However, if the old bulb is out, then you can swap the bulb from the other tail light. If it works properly, then the new bulb could have a different wattage. You should also perform a quick checkup on the battery because it may be low on power.

  • Toyota Tundra Tail Lights: Four Tips to Keep Them in Perfect Condition 27 February 2013

    The tail lights of your Toyota Tundra may not be as important as the radiator or flywheel of your pickup, but they play a big role in keeping your driving safe especially at night. However, the tail lights don't last a life time, and they will eventually show signs of wearing down through constant use. To help you maximize the service life of your truck's tail lights, here are some quick and easy maintenance tips:


    Clean the tail lights regularly.


    The cheapest, easiest, and probably the most effective way of maintaining your Toyota Tundra tail lights is by cleaning them regularly. The cleaning materials you'll need are automotive soap, clean rag or sponge, and water. Keeping the tail lights clean can prevent the accumulation of dust on the tail lights' surface and the formation of residue inside their plastic housing.


    Keep the tail lights' surface clean and clear.


    Over time, the surface of your pickup's tail lights will become dull and blurry because of harmful, natural elements like the sun's UV rays and hard rain water. You can solve this problem by buying new tail lights, or you can save some money by restoring them in your own garage. Some of the materials you have to prepare are fine sandpapers, basic cleaning solution, and plastic polish.


    Inspect the wiring of the tail lights at least once a year.


    You should inspect the wires behind your car's tail lights every year or when you want to clean the tail lights thoroughly. This will help you detect if the wires are already chipped and corroded-reasons of tail light malfunction. If there are some chipped wires visible, you can use electrical tape to cover them and a voltmeter to test the voltage if they're still good. Otherwise, you have to consider replacing the wires.


    Prevent condensation from entering the tail lights' housing.


    The formation of residue inside the tail lights is something that's difficult to avoid because of humidity and heavy rains. You can remove the residue by detaching the tail lights and letting them dry up, but it can get tiring when you do it over and over again. An effective way to keep them free from residue is by wrapping the outer portion of the tail lights with plumber's tape.
