Brake Lights wont work

I dont know what is wrong with my brake lights i replaced the fuse even though the fuse was still good just to see if maybe thats what was wrong with it but they still dont work at all i dont know what to do. Can anyone help me please? ASAP

check the switch that attached to the brake pedal, see if your getting 12+volts on both sides of the switch when u press the pedal down, and find out what color the wire is, and trace it back, the wire splits at the rear of the truck, the connection might have broke where they use a crimp connector to split the wire to both tail lights, ive had a problem like that in the past

check and make sure from ur tailights to the wires that run to ur cab or fuse box, didnt get spliced somewere, i no mine did the ground on my driver side got spliced and everytime id hit my brakes they would dim out.

I guess you need to shave them now
