Common Causes of a Brake Light Warning
There are several reasons why your 2008 Cadillac CTS might display a brake light warning. Some common culprits include:
- Burnt-out Bulbs: This is the most frequent cause. Brake light bulbs have a limited lifespan and will eventually burn out.
- Faulty Brake Light Switch: The brake light switch activates the lights when you press the brake pedal. A malfunctioning switch can prevent the lights from illuminating.
- Blown Fuse: A blown fuse in the brake light circuit will cut off power to the lights.
- Wiring Problems: Damaged or corroded wiring can disrupt the flow of electricity to the brake lights.
- Trailer Wiring Issues (if applicable): If you frequently tow a trailer, issues with the trailer wiring harness can trigger the brake light warning.
Diagnosing the Problem
- Check the Bulbs: Visually inspect all brake light bulbs. If a filament is broken, the bulb needs replacing.
- Inspect the Fuses: Locate the brake light fuse in your car’s fuse box (refer to your owner’s manual). Check for a broken filament in the fuse. Replace if necessary.
- Test the Brake Light Switch: You can test the switch with a multimeter or by checking for voltage at the brake light connector when the pedal is depressed.
- Examine the Wiring: Look for any signs of damage, corrosion, or loose connections in the brake light wiring.

How to Prevent Future Brake Light Warnings
Regularly checking your brake lights, along with other routine maintenance, can help prevent future brake light warnings. Replacing bulbs before they burn out and keeping the wiring clean and dry can also prolong the lifespan of your brake light system.
