brake lights not working

anyone know why I would have no power to my brake light switch turn signals working good but no brakelights
Hemi powered 1928 Farmalls do not have brake lights, and neither do 1943 Supermarine Spitfires





To put this another way, what are we working on, here?

Year, make, model

You can download wiring diagrams and factory service manuals free from MyMopar.com

Some of the guys right here are responsible for them getting there
