Lighting plays a vital role in every vehicle. They are essential for driving at night. With the help of lighting, you can see the car in front of you and those behind you. This helps to minimize road accidents at night.
Aside from that, the brake light notifies the driver behind you when you slow down by applying the brakes. Cars also have side lights. These lights are used when taking corners to notify other drivers and passersby.
To add in the line, the tail lights are also essential as they show the rear edges of the car and help the vehicles behind know the size of your car to avoid a crash. This article discusses mainly tail light vs. brake light contests which will make you clear about tail lights and brake light bulbs in the course of the talk.
So let’s dive right in to get authority knowledge on their meaning, differences, and similarities.
What is a tail light in cars?
Tail lights are red lightings at the rear edge of your car. They light on whenever you switch on the headlights. When driving, they have a dimmer red appearance but change to a bright red appearance when stopping.
As reiterated, taillights are located at the rear edge of the car, facing rearward. Some are built with reflective materials to amplify and make the light brighter. More states in America restrict the tail lights to red alone.
Tail lights work on a relay. So, the driver does not have to turn on the light. Instead, it comes on whenever you switch on the headlights. Tail lights are wired to the same headlight switch in cars, making them easy to turn on without pressing another switch. In short, what are tail lights used for, anyway?
To be precise, tail lights are a safety feature in vehicles. They project the rear end of the car so that other drivers behind you can see the back edges of your car and gauge the size. This undoubtedly minimizes accident rates at night.

What is a Brake light in cars?
Which lights are the brake lights? Like the tail lights, brake lights are red lightings at the rear end of your car. They come on whenever you depress the brake pedal and go off as you remove your foot from the pedal. They are placed in the same location as the tail lights but project brighter red lighting.
Depending on your car model, they may be placed in the same housing units. The brake light is a safety feature that alerts drivers behind you that you’re stopping or about to slow down, allowing them to adjust their speed or navigate to another lane to avoid crashes.
With functioning brake lights, the drivers behind you should distance themselves from your car when slowing down. Your brake lights tell the drivers behind you that you’re stopping or there’s traffic ahead and help them prepare on time.
Additionally, the brighter red brake lights make them more visible in rainy, snowy, dark, and sunny times.
Tail lights and brake lights share the same housing units. This may prompt many to ask, are tail lights and brake lights the same bulb? Different vehicles come in different designs. In some cars, the tail and brake lights share the same bulbs.
This doesn’t mean the tail light will come on when you depress the brake pedal. The bulb has two filaments that control these lights -one filament for the tail lights and the other for the brake lights. However, in some cars, the tail and brake lights have two separate bulbs that control them.
What is the difference between tail light and a brake light?
The primary difference between the tail light vs. brake light bulbs is that the tail lights come on once you switch on the headlights. If your vehicle is designed such that the headlight illuminates once you start the car, the taillights will also come on once you start the vehicle without pressing any button or switch.

They are mounted close to the right and left rear and front corners of a car, sometimes on the side mirrors. Some vehicles also have tail lights on sizes. They are activated on one side of the car, depending on where the driver is turning to.

This situation may be more confusing if your vehicle uses the same bulb for both tail and brake lights. However, there’s a reason and solution to this problem.
A blown bulb is the most common reason your tail lights work, and the brake lights are not working. If your car uses one bulb for both brake and tail lights, the bulb has two or more filaments. The filament controlling the brake light may be broken.
