Tail Lights Not Working (3 Reasons And Their Solutions)

We have compiled the most common scenario of tail light not working. Most owners have to deal with these issues. One by one, let’s get to it!

1. Fuse Problem 

Most often, tail lights do not work because the fuse has burned out. Fuses control the overflow of electricity. 

The headlights, brake light, tail lights- all have different inbuilt fuse boxes. So that you can easily identify your preferred one.


For your convenience, the solution is discussed in two easy steps. Follow them accordingly to solve the fuse problem.

Step 1: Locate the fuse box of tail lights

Right below a trim panel, you’ll find the fuse panel.

There are several fuse boxes in the compartment. But the one you’re looking for is under and to the left of the steering wheel.

Step 2: Opening Fuse Panel

Pull the trim panel toward you.  Swing it away from the side to remove it. The fuse panel will be visible to you.

The fuse panel lid can be removed by pressing in the tabs on either side of the cover. Peel it off when you’re done!

The top of the fuse panel cover should be placed on the fuse panel and secured. Press down the bottom of the cover until it locks in place.

Step 3: Replacing Fuse

Remove the number 7 fuse, that’s the fuse of the tail light. However, if it seems complicated to identify one, do a test. Pull every fuse and look for ones that have blown.

There are a few steps to replacing the old one with a new one: You may check if it is correctly locked by gently pulling on the fuse panel lid. Use a similar amperage when replacing.

Here are some of our top picked fuse in case you’re looking for good quality ones-

2. Burnt out Bulb Problem

Burnt-out bulbs are the most common scenario for every light of your vehicle. In this case, you have to replace the bulb with a new one.


Don’t worry, a burnt bulb can be easily fixed. You just simply need to replace it. we‘ve mentioned the steps below.

Step 1: Pull Out the Bulb Assembly

It’s necessary to remove the lens housing from the car before you can proceed. Phillips-head screws are commonly used to secure it in place. Keep them in a secure place.

Now you have to pull out the bulb assembly.

This bulb assembly can be pulled out of its hole, once all the screws have been removed from it. Don’t pull on the wiring excessively. Most assemblies can be removed as a whole, but others have an outer cover. 

Step 2: Unscrew the Bulb Holder

Assemblies like brake lights and taillights need a plug to retain the bulbs in place. In addition, the plug screws into the lamp assembly.

Using the wires as a guide, find the bulb holder on the rear of your light that needs to be replaced. Unscrew it by pulling it out.

Step 3: Pull Out the Old Bulb

Finally! An unlit bulb at the end of a long tunnel is all you need to see the light (or lack thereof). Replace it with a new one.

This problem can be avoided in the future by replacing the bulb with a high-quality one. Here are some that we found worth recommending. 

3. Tail Light not grounded

Electrical wires need to be grounded properly. It will circulate the extra electricity to the ground. If the wires are not grounded, the extra electricity flow causes damage to the light. Aftermath is a not working tail light.


Step 1: Finding the Ground Connection

The ground connection is located on the rear of each taillight. The trim panels in some trunks must be removed. 

You can do it with a Phillips-head screwdriver or a tiny socket. 

Step 2: Reinstall the Connection

Remove the screw that holds the ground connector to the vehicle’s body. Scrub the connector and car body contact area with sandpaper to remove all corrosion. This connector should be replaced with new solderless rings.

Here are our recommended sandpapers for your convenience-

Reattach the ground connector to the body of the machine. If the old screw is highly rusted, use a new one.
