How can you get your brake lights to work when you apply the brake?

The first thing that I would do is look at the arm of the brake pedal and make sure the arm is pressing against the brake switch, press the brake pedal with your hand and see if the switch head goes in. Also if you have someone with you have them watch the brake lights and use 2 fingers and press the head of the switch in and ask if the brake lights are on,it may be that the switch is bad. this would be step 1. depending on how old the vehicle is you may have a broken 12 volt wire or a ground wire, if your turn signals work and your taillights work I would first check the brake light switch. i have never seen 2 brake light bulbs go bad at the same time.


What is causing the brake lights not to work on 1997 Ford Explorer?

Check the fuse, bulbs/assy., and wiring another thing to check is where the bulbs connect. sometimes like my 94 one of the connectors in the bulb housing was broken. also there is a brake light sensor on the brake petal that is turned on when you depress the brake. usually near the top of the brake petal
