Hi All

New to the forum... hope I could get some pointers or advice on this issue...

Brake Lights not coming on when brake is pressed. I have hazards and turn signal lights but no brake lights. Checked switch at brake pedal and has voltage where it should. Have hooked a trailer to it, and the brake lights don't come on there, so I can't initially believe it is blown lamps.

Any ideas? What's the wiring path for the brake light circuit?
Would appreciate any and all help. Thanks.
