2.Blown fuse: A blown fuse can also prevent the brake lights from working. Fuses are small, cylindrical devices that are designed to protect electrical circuits from damage. If a fuse blows, it means that too much current has flowed through the circuit and the fuse has melted to stop the flow of electricity. In the case of the brake lights, the fuse that is responsible for them is usually located in the fuse box under the hood or dashboard.
3.Faulty wiring: Faulty wiring can also be a cause of brake lights not working. The wiring that connects the brake light switch to the brake lights can become damaged or corroded over time, which can prevent the brake lights from receiving power.
4.Faulty brake light bulbs: If the brake light bulbs themselves are faulty or burned out, they will not be able to light up when the brake pedal is pressed.
5. Faulty Brake Light Relay: Some vehicles have a brake light relay that controls the power supply to the brake lights. If this relay is faulty, it can prevent the brake lights from working.
