Frequently Asked Questions on Brake Light LED Bulbs

If you’re planning to upgrade your brake lights to LED bulbs, you might have a few questions. We’ve developed a FAQ section that outlines core questions and answers regarding brake light LED bulbs:

Are taillights and brake lights different bulbs?

Since taillights and brake lights both sit in the rear of your vehicle, you might be wondering if they use the same bulbs.

Most vehicles take advantage of a single bulb design - but the bulb consists of two filaments. A low filament will stay on while driving (taillight) and a brighter filament will activate when you touch the brakes (brake light).

Do LED brake light bulbs need resistors?

In most cases, brake lights do not need resistors. However, if the brake light bulb is the same bulb as the turn signal, then it will need resistors.

Do brake light bulbs need to be red?

If you’re planning to buy new brake lights, you might be wondering if they must be red. Yes, having red rear brake lights is a legal requirement in all 50 states in the United States.

The states have mandated this color for a variety of reasons. Firstly, humans can identify red colors well from a great distance, making red lights an excellent tool for warnings. Also, red has long been a color associated with warnings. Standardizing this color is critical to keep everyone safe.

Also, if you change your brake lights to white (with your existing red lens), this will turn into a soft pink color.

Can you have different color brake lights?

No, you cannot choose a creative brake light color. By law, your brake lights must be red in all 50 states within the United States. This includes brake light LED bulbs.

Is a taillight and brake light the same?

No, taillights and brake lights are different lights with different functions and appearances. Your car has many lighting systems, including turn signal lighting, brake lights, headlamps, taillights, and more.

A taillight helps mark the rear of your vehicle when you’re driving, especially after dark. Brake lights are much brighter and only activate if you apply your brakes as a driver, which helps warn people behind you that your car will slow down.

People often confuse taillights and brake lights because they’re both red and they’re both at the rear of your vehicle.

Why are my brake lights not working after replacing the bulbs?

If your brake lights aren’t working after changing the bulbs, the problem could be due to various factors. The bulbs might be faulty, or you could have issues with the wiring in your brake system.

Also, if your turn signal and brake lights share the same circuit, a faulty turn signal might be the reason your brake lights aren’t working. It’s best to speak to a mechanic if you’re unsure why your brake lights aren’t functioning correctly, as this can also be the result of a faulty fuse.

How can you tell if a brake light bulb has blown?

If you have brake light LED blubs installed on your car, they might have blown if your brake system is not activating the lighting. The best way to determine if your brake lights are functioning correctly is to check them once a week. Have a friend stand behind your car while you press the brakes and let you know if they are functioning correctly.
