The most likely cause is a bad brake light switch (if none of the brake lights illuminate) but if its only one of the brake lights, try changing the bulb. Even if they still work as running or turn lights because they have a double filament and may still work partially, but not as brake lights.


No. The one in the middle is a brake light, and should only come on when you put on the brakes.


You need a minimum of 2 brake lights, So if your car has 3 brake lights and one goes out, you are still legal. Some cars do not come equipped with 3 brake lights but others do such as a honda civic with a spoiler light do.


It depends on the exact problem. If it's that both brake lights in the back do not work and the middle one works, it could be your turn signal switch.


TRY TURNING THE EMERGENCY FLASHERS ON AND OFF A COUPLE TIMES THEN CHECK YOUR BRAKE LIGHTS. WORKED FOR ME.


Depending on the year, there may be one fuse for all three brake lights, or two fuses, one for the highmount brake light and one fuse for the two lower brake lights/tail lights. So, if all three brake lights are out, it could be just one fuse or perhaps the brake light switch which is on the brake pedal metal arm assembly.


Look for a fuse labeled TAIL LIGHTS. There are 2 separate circuits, one for brake turn and flasher and the other is for tail lights.


Many cars use the same bulb for the brake and turn indicator. Seems like one is burnt out. Have someone step on the brake and see if one of the brake lights does not respond.


put your foot on the brake pedal and press down while some one looks at the brake light to see if it lights up


Nonfunctional Brake LightsOne possible cause of this issue is that the brake light switch is not adjusted properly, or the switch could be defective.


Something you may not realise is that the brake light bulb is often one bulb with two elements. One of the elements will be for the brake and the other will be for the tail lighting for example so,when tested, the actual bulb will still light up because the second element is unaffected. Make sure that the 'blown' bulb that you are actually changing is not in fact your fog lamp. This will not automatically light up when you test your lights as you have to operate this light separately (similarly to indicator lights). So the fog lamp bulb will appear to be the only one not lit up when you test your lights. Find the bulb with two elements inside and change that one. Sounds obvious (and may be obvious to many) but it's a common mistake. Hope this helps!.



Your trailer tailights are dual-filament, with one being the running lights and the other the brake lights. You need a separate power source from your towing vehicle's brake lights to power them. The easiest way to do this is go to U-Haul and but a set of their trailer towing taillight bulbs for your towing vehicle. The bulbs replace your standard tail/brake light bulbs, and they have two wires coming out of the base of the bulb. One of the wires connects to your trailer's running lights, and the other one connects to your trailer's brake light circuit. I'm trusting that when you re-wired your trailer, you ran two wires from the taillight socket, one for the running lights and one for the brake lights. In some trailers, the brake light circuit also doubles as your turn signals. Good Luck.


a crappy car. my 99 beetle has the same problem. brake light switch new, bulbs and fuses new. brake lights just work whenever the heck they want. this is one of the many reasons my car has a for sale sign in the window. good luck.



The tail light/brake light bulb has two filaments. If one of the filaments is broken, you will get either only tail lights, or brake lights. If a new bulb doesn't work, then you have a broken wire or bad connection in your plug-in.


It's in the fuse box under the dash. Look at the cover of the fuse box and it should tell you which fuse is brake lights and horn. On my Legacy it is the middle row, third one in, fuse 12 I think.


Nonfunctional LightsI'm not familiar with your 2002 Gran Prix, but the problem you describe is universal to all vehicles.The fact that the "third" brake light [in the rear window package tray] IS WORKING, indicates that the brake light switch IS WORKING properly!!!!!That suggests that the reason that the other two brake lights are not working is that there is an "open" condition in the wiring circuit to the other two brake lights. This is confirmed by the fact you replaced the lamps [bulbs] in those other lamp holders with known good lamps.There could be several causes for an open circuit, but the most common include:One of the connector plugs in the wiring harness to the brake lights has become disconnected, orCorrosion has built up inside of one of the connectors [one that feeds both brake lights, which will be in the circuit "ahead" [upstream] of where the wiring harness "splits" off between the two brake lights].Very remote is the possibility that the ground wires on both light assemblies has been disconnected, cut, or corroded.


its probably not a fuse at all, but it could be your brake light switch. its under the dash hooked to the pedal. I had to replace one on my 84 t-bird


Check bulbs they are double filamented with smaller for brake lights Could be a problem in steering column


It means one of your rear brake lights are out. Not the tailights but the brake light(s).


I have a 79 ford chatou 12 seater van. everything works the bulbs are good but the brake lights wont turn on when I step on the pedal. whats up? if its my brake switch should I change it out? or can it be fixed also which fuse is my brake lights? wouldn't the lights all be on one fuse?

You do not need the key in the ignition to make lights work. They are "hot" all the time. The reason you Sid marker lights are coming on at the same time is because you have a bad ground in one of your brake lights. It's allowing electricity to jump from the brake lights to the tail light circuit. Take the brake lights apart, clean up all the rust and make sure they "ground" to bare metal. Problem cured.


If your 98 Monte Carlo brake lights do not work when you hit the brakes, but the top one behind the glass works, check the bulbs. If the bulbs have burn out, the lights will cease to work.
