check your parking light grounds,lights are trying to ground back thru the circut .common to lose ground in the light socket or even a shorted bulb. most part stores have replacement sockets
This will happen if the ground terminal for the brakelight bulb is connected to the power side by accident. If you have a 3 wire socket or light assembly with GROUND, TAIL, and BRAKE wires two of them are wired incorrectly. When the headlights are off the brake light is finding ground thru the filaments of the headlights. Since the headlights have much heavier filaments, they provide a good ground for weaker brake light. When power is on the headlights the brake light will have power on both sides, so no current flows and it goes out.
The brake lights and the tail lights are separate circuits. Check the brake light fuse, then check the brake light bulbs, then check the brake light switch.
Check the bulbs one of the 2 filaments may be burned out
the light doesnt go through the fog
WHAT ARE YOU DUMB REPALCE YOUR LIGHT BULBS STUPID! Not stupid replaced circuit boards checked fuses ran test light . When headlights are on no brake light or taillights and have all new bulbs stupid. Turn headlights off brake lights work, so figure that out smart man
The brake light switch can be found below the dashboard on the drivers side of the passenger compartment. The brake light switch simply plugs in and out.
The ground for the brake lamp. When the tail lights are off, the tail light circuit can act as a ground for the brake light. When the tail lights are on, it can't.
check brake light switch
You can only turn off the headlights by applying the emergency brake. When the emergency brake is on, the headlights will not light. Otherwise the best of my expererience is that they are on all the time. If you have remote start, put the emergency brake on before you leave the vehicle and when you remote start it, the headlights will not be on, but the driving lights (if switch is on) will be on as well as the parking lights.
The only way your headlights can come on when you press on the brake pedal is a crossed wire. The brake light wire and the headlight wire can be frayed and touching each other.
You have blown a fuse, look for an acc. fuse out.
If it is just ( 1 ) lower brake light that is not working it is probably the bulb
probably bad headlight switch,the break light wires run through the headlight switch
If it's like a 1996 tracker the headlights won't come on unless the parking brake is released or the light switch is on.
Bad fuse or bad brake light switch.
You probably have a loose wire connection in the brake light sockets. Insert a nail or probe tip into the back of the light socket where the wires are inserted and test the brake lights. (The socket can appear perfectly normal and the wires may even seem well attached.)
The head light switch is shorting out ,or a bad connection
I dont know because i dont have a FORD Check your brake light switch on the back of your brake pedal for adjustment.
Nonfunctional Brake LightsOne possible cause of this issue is that the brake light switch is not adjusted properly, or the switch could be defective.
Check the ground wire to the tail lights.
Check the brake fluid reservoir, with some vehicles they share the low fluid light and the e-brake light.
Sounds like the brake light switch is defective.Sounds like the brake light switch is defective.
the brake lights are on a separate cuircut,if your brake lights are staying then it will be a fault with the brake light switch. the switch is located under dash,and will be on or very close to brake pedal.
Shouldn't have anything to do with it. The brake lights are on a completely different circuit than the headlights. If your brake lights are not working check the switch on the brake pedal. Before you do that check the fuse first. If the fuse is all right it is probably the brake light switch which is bad. Check the bulbs to see if they are burned out. If you can't tell, replace them anyway. If the Brake switch is good and the fuse is good, you may have a loose wire, or a bad wire.
