The third brake light on your 2005 Chevrolet Tahoe is an essential safety device that illuminates when you press the brake pedal. It helps avoid rear-end collisions by alerting other drivers that you are slowing down.
A third brake light is an affordable, effective addition that can make a big difference in road safety. Voevodsky, a psychologist, conducted an experiment with third brake lights in San Francisco taxicabs and discovered they reduced rear-end collisions by 60.6%.
What is the Brake Light Switch?
The Brake Light Switch is an electrical component that controls the brake lights’ operation. When you press on the brake pedal, it activates and supplies power to your lights in order to alert other drivers that you are about to brake.
Your brake lights are an integral part of vehicle safety, so it’s essential that they work correctly. If the brake switch malfunctions, your lights may not come on at all or remain illuminated for an extended period.
Your brake light switch may malfunction for several reasons, including wear on the internal switches, poor connection terminals, misadjustment or damage to your brake pedal assembly.
No matter the cause, it’s important to get your brake light switch replaced as soon as possible. This common repair can be accomplished quickly and easily with the assistance of a reliable shop.
Brake Light Switch Repair
When the brake pedal is depressed, a switch activates which sends an indication to the lights at the rear. Replacing this simple electrical component doesn’t take much effort and cost-effectively too.
The switch’s plunger acts as a conduit between two circuits, allowing power to flow from the battery to illuminate brake lights. Over time, however, the plunger may become loose or break, leading to misaligned circuits and inoperative lights.
To determine if your brake light switch is defective, you’ll need to test for voltage and ground. This requires using a multimeter and testing the circuits within the switch itself.
If there’s no current on your voltmeter, then your switch is likely defective and needs replacement. But if there is current present, something else needs to be addressed before replacing the switch; this will help identify the source of your issue so that you can quickly resolve it.

The brake light switch is an electronic component that supplies power to the signal lights at the back of your car, alerting other drivers that you are slowing or stopping. This function is essential for safety as it helps avoid rear-end collisions.
When pressing the brake pedal and the brake lights don’t illuminate, this could be indicative of a malfunctioning switch or another issue in your vehicle’s electrical circuit. Usually, you should check first the fuse box for your vehicle.
The brake light switch is usually located under your dashboard, above the brake pedal. Depending on your car model, it may be wired into either your gear selector or shift interlock mechanism.
