What is the problem when head lights are on and the tail lights dont work but the brake lights work?
If the headlights are on and brake lights work but not the tail lights, it is possible there is a short in the electrical wires.

The right tail light and signal blinker work on your Toyota highlander but the right brake light does not How do you fix the problem?
Hmmm, kind of unusual because the same bulb filament serves BOTH the blinker and the brake function. It could be a short in the wire from the brake switch leading back to that particular bulb and if the left brake light work okay it would have to be somewhere AFTER the wires leading to the rear lights branch off from one another. Are you CERTAIN that the right rear signal blinker DOES work?

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…

I would check the rear bulbs. I just had this issue and it ended up my brother had used the wrong bulb, and odd enough it caused the brake lights to stay on with headlights. When headlights were not on and you applied the brakes the dash would light and brake lights worked. Strange, HUH? I must admit before this revelation, I replaced headlight switch and brake switch, with no avail.
How do you repair brake light short headlights on no brake lights just the cyclops lights off brake lights and cyclops all bulbs new and correct no obvious wire damage or switch wear?
Your question was a little unclear, does the brakelight work when the headlights are off but not when they're on? If that's the case, it's a ground problem. Check the ground to the tail light/brake light assembly. If the brake lights don't work at all, check the turn signal switch. Brake lights are routed throug the turn signal so that you can use the same bulb for turn signal and brake light. BTW, if you…
