This usually means a bad or wrong bulb in the tail lights
On a toyota tacoma 2003 SR5 when the tail lights are turned on the brake lights come on and when the tail lights are of the brake lights work just fine what could be the problem. If the truck has a trailer plug, inspect the plug and plug wiring for damage and corrosion.
I just had my Daewoo Leganza brake light switch replaced. It goes under the brake pedal. and now my brake lights work fine.
The brake lights may not work on a 1993 Honda Prelude if the brake light switch is no longer working. The brake light switch is in the steering column just above where the brake pedal is bolted to it. There is also a chance that a brake light fuse is blown.
Check the fuse for the brake lights. It should be marked stop/haz on the fuse box cover.
Brake bulbs. You might need to replace them. It just happened to mine and it was tricky to do it. To take the brake lights you need to pull them from the sides, there is a small piece that would come out easily and then you can just take the screws out.
you probably need to lift up on the brake pedal a couple of times to reset the brake switch. worked on our 86
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.
No , the rear brake lights do not turn on when you use your parking brake , just the brake light on your dash is supposed to come on
Check the alternator capacity.
Turns out it was a relay. I just switched the one for the fog lights(not equipped) with the one for the chmsl and it works fine
IT'S PROBABLY JUST A PROBLEM WITH THE PRINTED CIRCUIT BEHIND THE DASH.
the turn signal switch is probably bad
