Brake light problem

can anyone tell me what the problem of my brake lighting? everytime i change the brake switch is ok but after a few days it does not work again.

check the wiring. I mean apply the current directly without using switch & c whether U brake light is on or off.

What is the condition of the brake switch after you’ve removed it? Burnt or smell of burning? If so, your car brake wiring could have low insulation or a slight short with respect to car body causing excessive current through the switch contacts but the current drawn is not enough to blow the circuit fuse. Use a length of sufficient size cable to run externally to the brake lights to bypass internal wiring to see if the switch still go bad.

thanks lot of the opinion…i’ve sent my car to check now waiting for the result…
