Hey guys. I have 03 350z last day i notice my brake light always on when i Turn on the lights. When lights Are off i press the Pedal and they works fine

Lights on brakes turn on lights off brakes turn off no dash lights , brake fluid good ,pads are good rubber Stopper and thr switch also fine.


Any ideas?

 

Just a guess, but it sounds like the signal for the rear running lights or parking lights is crossed to the main brake light signal.

Unless you're referring to the rear running/parking lights - those should be illuminated whenever the parking/headlights are turned on.

Have you made any electrical wiring changes recently?

 

Found the Problem. It was a tail light bulb

 

burned out and the filimemt touched another metal part inside ?

 

Maybe the wrong bulb. Some bulbs have the same base, but the circuit is reversed.

 

Youre right filimemt touched another metal part
