my brake lights are bright when my headlights are on like if you was pushing on the pedal but the third brake light don't come on i need help tryed everything new brake switch, fuse is good and all bulbs are good

 

You may have the bulbs placed incorrectly in the socket. When that occurs, the wrong filament lights up (in this case the brighter one), and it may appear as if the brake lights are on. Make sure you match the pattern on the inside of the socket with that of the bulbs. The bulbs have these small notches, and one is higher than the other.

Hope this helps.

 

thanks but i didn't touch any bulbs it just happen one day I was driving and I backed up into the drive way and my mom said your brake lights are still bright with I got out.

 

So the car was off, and the lights were still on? Did you properly adjust the brake light switch? Thread in the switch too much and the lights won't come on. Thread in too little and the lights stay on. It might be the latter if the switch is not adjusted correctly. This would also cause the brake lights to stay on even with the car off and the brake pedal not pressed. Hope this helps.

 

If when this happens, the third brake lamps do not light up, but in normal braking operation they do light up, the problem may be in the hazard/turn switch circuit. When this happens, do the front ones light brighter also?

 

no they dont get brighter but is a new column. but it was doing when i had to old column in.
