Tail lights are essential car safety features that alert you when other drivers are nearby at night. This helps to reduce car collisions at night. If you have a broken tail light, it’ll impair your visibility at night, increasing the risk of road accidents.
Fortunately, tail lights do not break often. Or at least, you can prevent them from breaking by taking preventive measures. And the replacement procedure is simple that even a DIY and amateur mechanic can handle it.
This article will explain how to fix a broken tail light, its causes, and why you should fix it. We’ll also discuss broken tail light costs. But first, let’s see the common causes of broken tail lights.
What causes a broken tail light?
Like other mechanical and electrical car system components, a few factors can cause a broken tail light. Let’s see the common and most prevalent reasons a tail light will stop working.
Most electrical and electronic system components have fuses that control them. These fuses prevent the electrical or electronic components they’re guarding from blowing up when there is a power surge.
These fuses have a simple design of two terminals and a tiny metal strip across the terminals. One terminal receives electric flow from the electrical system and transmits it to the other terminal through the metal strip across them. The second terminal directs the electric current to the component they are guarding.
If there’s a power surge in the system, the tiny metal strip across the two terminals will cut, preventing voltage from transferring to the principal component they are guarding. This will prevent the critical component from damaging and also prevent it from working.
Typically, this can be the reason your tail light stops working. We published a well-detailed article that explains what a blown 30-amp fuse looks like. Check it out to know what any blown fuse looks like.
The light bulbs in your car will eventually die under regular use. They do not last the lifespan of the vehicle. And tail light bulbs are no exception. If you suspect a dead bulb is why the tail light stopped working, remove the broken tail light cover and inspect the bulb inside.
Inspect the bulb by looking at it. If it has loose wires, or it is black and scorched or has a broken filament, the bulb is dead and needs replacement.
Faulty tail light socket
The tail light bulb socket can malfunction due to rust or debris. It can also deteriorate or stop working due to a short or open electrical harness.

How do you fix broken tail light?
Since several issues can cause tail lights to stop working, there are several ways of rectifying the problem. We’ll look at these methods and see how to fix broken tail light plastic covers and the light.
Inspect and replace the damaged fuse
As explained above, the bulb will stop working if the tail light fuse blows. If this is the leading cause, replacing the light bulb will not rectify the issue until you track and replace the blown tail light fuse.
Firstly, you have to find the fuse, locate the blown fuse and replace it. The fuse box is usually located under the steering wheel and in the engine compartment, close to the battery. It is a black rectangle box with a ‘relay & fuse’ inscribed on it.
The fuse box cover has a diagram that indicates what each fuse controls. Locate the one controlling the tail light and replace it. This is all you need to repair a broken tail light if it is the root cause.
Inspect the tail lamp wiring harness
The tail light fuse connects to the light bulb through the socket wiring harness. Inspect these wires through the lid on the trunk to see if they are loose, frayed, burnt, or damaged. If the wires are loose, reattach them. If they are frayed, burnt, or damaged, replace the wires.
Inspect the taillight bulbs
If diagnoses prove the fuses and the wiring harness are in good working condition, the light is likely the root cause. Remove the plastic light cover with a screwdriver to examine the taillight bulbs. If the cover does not have screws, see if it has clips or if you can asset the light bulbs from the trunk.
Unscrew the bulb from the socket and inspect it. Look at the filament inside the bulb and see if they are intact. If you’re unsure if the bulb is still in good condition, slightly tap the light bulb on your hand and see if any particles are vibrating or moving inside the bulb.
Replace the bulb once the inspection confirms you have a blown bulb. You can get the replacement online or from nearby local auto spare part shops.
Examine the taillight plastic cover
After checking and rectifying issues with the fuses, wiring harnesses, and light bulbs, examine the taillight plastic cover and ensure they are in good condition. If the taillight cover is cracked or broken, it’ll allow water passage into the bulb housing, causing the bulbs to burn out prematurely.
Since leaving a cracked or broken taillight will cause premature bulb burnout, we’ll explain a temporary fix for a broken tail light cover to prevent water from entering the housing.
However, you can replace the tail lamp or search for “broken tail light repair near me” to help experts fix the broken lamp.
Fix the cracked or broken tail lamp
Get a lens repair kit. Firstly, remove the cracked tail lamp using a screwdriver. After that, clean and dry the cracked surface with a clean cloth. Then, re-clean the surface with a lint-free towel wet with alcohol, and allow it to dry.
Now, cut a lens repair tape slightly bigger than the cracked surface. Place the lens repair tape on the cracked or broken surface. Take off the lens backing plate and let it smooth out the air bubbles. Kindly, note that this is a temporary fix, as I explained earlier. So, you’ll have to replace the tail lamp when you have the money.
Fix broken or gouged surfaces with lens repair resins
If there’s a hole or gouged surfaces on the tail lamp, get a lens repair kit that has resins for filling gouged or broken areas. You can get lens repair resins at an online or nearby local auto store.
To fix the gouged spots;
- Grab a lens repair tape that comes with the repair kit and tape the outside of the lamp to hold and prevent the resin from leaking when you apply it.
- Put on protective gloves and mix the resins with a coloring agent and a catalyst. Read and follow the instructions on the repair kit.
- After mixing the resin, grab the syringe and pour it into it.
- Spray the resin into the gouged spot and let it sit for two hours.
- Take off the tape on the other side and sandpaper the surface.
