Maintaining your brake light bulb is essential for both your own safety and that of other drivers, helping to avoid accidents and tickets.

Your Hyundai Elantra’s factory incandescent third brake light emits a soft glow that takes a moment to illuminate. An LED upgrade provides instant response time, alerting other drivers on the road ahead and giving your car a contemporary LED appearance.

Brake Light Switch

The brake light switch regulates the flow of current from your car battery to your tail lights. When you press on the brake pedal, this circuit is opened and closed again by releasing it.

If this switch malfunctions, your brake lights may not illuminate or they may remain illuminated regardless of how hard you press on the pedal. This poses a serious safety risk and could result in an accident.

Brake light switches can become worn out if they become exposed to dirt, dust or water. This is particularly common in stop-and-go traffic where the switch body is placed close to a driver’s feet and could potentially fail due to contact with dirt, dust or water.

If your brake light switch is malfunctioning, it is best to contact a mechanic right away. Doing this will guarantee that your vehicle receives proper investigation and you can have a replacement installed quickly.

Brake Light Bulb

Brake lights, located behind the rear bumper of your vehicle, alert other drivers of when you are slowing down. Without them, you could get into an accident and be stopped by a police officer for questioning about speeding tickets.

Before going for a drive, always inspect your brake light bulbs to make sure they function correctly. They should illuminate when you press the brake pedal and be able to shine brightly.

If you notice your brake lights are dim and failing, it could be time for a replacement bulb. Be sure to select the correct type of bulb for your particular vehicle.

For cars and trucks, the three primary light bulb types are halogen, xenon, and LED. Each is designed to deliver a specific amount of brightness and last a specific number of hours before burning out.

Brake Light Socket

The Brake Light Socket is a small component that connects your Hyundai Elantra’s brake lights and rear reverse lights. You’ll find it located on the lower tail lamp assembly.

The socket may not be the most stylish piece of automotive engineering, but it ensures your lights work for years to come. There are a few steps you can take to keep it in optimal condition.

1. Utilize a white vinegar rag to gently wipe away any rust from inside your brake light socket.

2. Create a baking soda paste that looks similar to the rag method but with more intensity.

3. Check for power at your socket with an auto parts store tester.

If your tester doesn’t light, there could be a wiring issue and you should consult with your mechanic. On the other hand, if two out of the three contacts light up, it is usually indicative of a strong socket.

Brake Light Wiring

In most vehicles, brake light wiring is connected to the Body Control Module (BCM). This serves as the central command center for all aspects of vehicle electrical system operation – including brake lights.

Through this connection, a circuit is run to supply the brake light switch with enough current to turn on and off its lights. In older cars, this same switch may send signals to additional controls like cruise control, ABS, traction control and shift lock control as well.

A malfunctioning switch may cause the brake lights not to illuminate when the pedal is depressed. This can occur if it isn’t placed correctly or is broken or worn out.
