What Causes the Brake Lights on a Ford Mondeo to Stay On Constantly?

[StLaila]

In most cases, the reason the Mondeo's brake lights stay on constantly is due to a burnt-out bulb. If replacing the bulb doesn't resolve the issue, check the fuse, wiring, and switch. For the headlights, you can visually inspect the color inside the bulb—if there's no discoloration or debris, the bulb is generally good. If both lights fail to work simultaneously, it's usually a switch-related problem. Additional Information: Automotive design includes three brake lights at the rear of the vehicle: left, right, and center (high-mounted light). The circuit switches for these three brake lights are connected to the brake pedal and are independent of whether the car is started or turned off. When the brake pedal is pressed, all three lights illuminate; when the pedal is released, they turn off. If the lights remain on after releasing the pedal, the fault lies in the pedal connection mechanism. If you're unsure how to fix it, seek professional repair.
