The automotive lighting system is an integral part of your car’s safety mechanism. Car lights are not just installed in cars as aesthetic accessories. Each of them serves a purpose, usually either to illuminate the road or to serve as the car’s signaling device. One of the most crucial components of a car’s automotive lighting system is the tail light
What Are Tail Lights?
Tail lights are one of your car’s safety components. They illuminate the rear end of the vehicle, warning other drivers about the distance between you and them. This is crucial, especially during low-visibility conditions. They also allow other drivers to properly estimate your vehicle’s size and shape.
In most cars, brake lights share the same housing, but these two lights serve different purposes. Brake lights illuminate only when you apply pressure to your brakes, while tail lights turn on along with your headlights or whenever your parking brake is on. The brake and tail lights are all parts of your vehicle’s rear lighting.
Although some brands offer different shades, most states strictly require the use of red tail lights. Since tail lights work simultaneously with headlights, these two are wired together. Automatic vehicles are fitted with automatic headlights that turn on during ignition.
Where Are Tail Lights Located?
Tail lights are attached to the rear section of the vehicle. They usually come in pairs (left and right).
What Are the Types of Tail Light Bulbs?
There are three common types of bulbs used for tail lights: halogen, LED, and xenon. Each bulb has its own advantages and disadvantages, and it's important to know them before deciding which is best for your vehicle.
Halogen Tail Lights
Halogen tail lights are a standard in most vehicles due to their affordability. This type of back light uses halogen gas mixed with tungsten-halogen filaments to generate light. One of the disadvantages of a halogen tail light is its lifespan. It only lasts for about 18 to 24 months, while a high-quality LED light can last for years.
LED Tail Lights
Although LED tail lights are more expensive than their halogen counterparts, they offer more benefits compared to halogen lights. This makes them a popular choice among vehicle owners.
LED lights provide better visibility than halogen bulbs. They also boast better energy efficiency. LED tail lights only require a minimal amount of energy compared to other light bulbs. This creates less stress on your car’s battery, which reduces repair expenses.
LED tail lights are also easy to install, requiring less wire splicing during installation. In fact, a lot of LED tail lights installations simply involve plug and play. If you have LED lights installed, they will be easy for you to replace with new ones if necessary.
Xenon Tail Lights
Cars rarely use Xenon bulbs for their tail lights because they are bright and irritating to the eyes. They are also expensive, and only professionals can install them.
These are just some of your options. Weigh their pros and cons to determine the ideal bulb type of your replacement tail lights.
Apart from the bulb being the major component of the tail light, most car owners also consider the color of the tail light’s housing. There are a number of variants available when it comes to this. Most come in shades of dark black or chrome.
What Are the Signs of a Faulty Tail Light?
If you are always the one driving, it will be difficult for you to detect a faulty tail light. Ask someone to stand outside and check while you turn on the headlights. If the tail light is working well, it will turn on at the same time as your headlights. Otherwise, there may be something wrong with it.
You can also activate your brakes to make sure your brake lights are working well. If your tail lights are dim or cloudy, have them checked immediately.
Don’t put off the checkup. Remember: having a faulty or busted rear tail light assembly is considered a traffic violation in most states. It also increases the risk of collisions and other road accidents.
How Much Does a Tail Light Cost?
The average cost of a tail light bulb would be around $20 to $100. Replaceing the whole tail light assembly would cost around $200 to $2000 depending on the inclusions and the type of bulbs used. This does not cover replacement and installation costs. Car tail lights are sold individually or in sets of two or four, as it is advisable to replace these lights all at once.
How to Install Tail Lights
Whether you are replacing a broken tail light or simply want to switch to a more cost-efficient aftermarket version, it would be much cheaper to do the installation on your own. Replacing vehicle tail lights is not as hard as it sounds, especially if you have the right tools (a wrench or screwdriver) and DIY know-how. It only takes an hour or two to accomplish.
Step 1: Ensuring a safe installation
Make sure that the ignition is turned off and the negative battery cable detached from the battery to avoid the risk of electric shock when installing the tail light.
Step 2: Removing the paneling
Open the trunk of your car and remove the paneling needed to gain access to your tail lights. These panels are often secured with screws, so have a screwdriver ready.
Step 3: Removing the bulbs and wires
Pull out the tail light bulbs and wires from the tail light housing. Be extra careful when removing the bulbs to avoid breaking them.
Step 4: Taking out the housing
Unbolt or unscrew the tail lights from the car. Once all the screws or bolts are removed, pull the housing out from the outside of the car.
Step 5: Installing the new tail light
With the old housing out of the way, put the new tail light housing in its place. Secure the housing with the appropriate nuts or bolts. Most tail light assemblies come with screws and other installation hardware, although you can purchase them separately as well.
Step 6: Returning the bulb and wires
Attach the new bulb and wiring to the new tail light housing, then replace the paneling you removed earlier to access the tail light in its place. Test the tail lights to check if they have been installed properly.
Several states have strict regulations on the use of aftermarket vehicle tail lights. Make sure that aftermarket tail lights are legal in your state before installing one in your car.
