Driving without headlights, tail light or light over your license plates is a federal offense in all states. If you don’t know how to check to see whether the tail lights are broken or not, then this article is for you. We’ll not only show you how to check them but give you a lesson 101 on how to replace a broken tail light. You don’t want to miss out on this.

What Exactly Are Tail Lights?

tail lightTail lights are the red lights found at the back of your car. Their main purpose is to serve as a warning/indicator to the cars behind that there is a car in front. They should be on whenever your parking lights are on or whenever your headlights are on. The majority of rear-end accidents are the result of the front car’s lack of working tail lights.

When your tail lights are working, they should be visible 1000 feet away so that cars behind you have ample time to adjust their speed if need be. This is particularly important at night and when driving in bad weather.

What Causes Tail Lights Broken And How To Know?

There are four main reasons why your tail lights might not be working: burnt out bulbs, a blown fuse, a bad brake light switch, and or a bad relay.

Broken brake light switch: if your rear lights are on but don’t shine brightly this might be the result of your brake light switch not working well.

Burnt out bulbs: if only one of your rear lights is off, it might just be because of a burnt out light bulb

Blown fuse: a crack in your tail light can allow moisture in, which can short circuit the tail light system causing the fuse to blow out.

Bad relay: Power is transferred from your car’s battery to the rest of the car through a series of relays. The tail lights also have relays that transmit power. When relays fail they could lead to non-functional tail lights.

A step-by-step Guide On How to Fix A Broken Tail Light

Contrary to popular beliefs, you don’t need a mechanic to fix your broken tail lights. This is something you can easily do yourself. We’ve put together this guide to help you do just that.

3.1 Assessing the situation and replacing the whole tail light assembly

The first thing you need to do is assess the situation and find out where the problem is exactly.


Do you have a blown fuse on your hands? Turn the car off. Find the fuse box using the car’s owner manual. Open the fuse box and look for the tail light fuse. If the fuse is still intact then you’re all good, if the metal inside the fuse is broken, however, then you’ve got a blown fuse. Get your fuse extractor out and gently pull out the dead fuse. Go buy a similar model at your local car parts dealership, and replace it.

Bad relay

You’ll need to locate the tail light wires that run from the battery to your tail lights. Check inside your trunk, you’ll find them there. See if there is any detachment. If there is, simply re-attach the wires and you should be good to go.

Burnt light bulbs

Using a screwdriver remove the tail light lenses and check to see if the filament wire is unbroken. The easiest way to check is to simply tap the light bulb gently too see if the inside wire is moving. If the bulb is indeed blown, go to your local car spare parts dealership and buy the right bulbs for your car type.

Inspect tail light lenses

– Remove the entire tail light lens

– Clean the lens using rubbing alcohol and a lint-free cloth

– Cut a generous length of lens repair tape and cover the crack

– Note that this is a temporary fix

If your tail light has a hole in it, this is how you go about fixing it:

– Purchase a lens repair kit which must include plastic tape, lens repair resin, the coloring agent, catalyst, and syringe

– Cover the area around the hole with plastic tape.

– Prepare the plastic resin by mixing the resin, catalyst and coloring agent together

– Fill the syringe with this resin and fill the hole with the substance

– Ensure that the hole is completely filled

– Allow the plastic resin to set for two hours

– When it’s all dry, remove the plastic tape and clean the surface with a lint-free cloth

Tail light accessories Recommended

led tail lightsWhy settle for regular, ordinary tail light bulbs when you can have LED tail lights? LED tail lights are significantly brighter and better looking than their regular counterparts. That’s not all; here are some further reasons to consider making the switch from incandescent bulbs to LED.

LED Tail Lights

LED Tail Lights are safer. LED tail lights illuminate 0.2 seconds faster meaning cars behind yours are able to brake and avoid potential accidents quicker.

LED tail lights last longer: LED tail lights because of their innovative, low-energy consumption are expected to last up to 60,000 hours. That’s a whole lot longer than the 2,000 hours expected of regular tail light bulbs.
