I have a problem with the brake lights..it seems when i activate the pedal the lights go off when the deactivate the pedal the light go on..i have the adjustable pedals on this vehicle..When i adjust the pedals the lights seem fine then the problem comes back a few days later..anybody know what causes this and how to fix...and is it an exspensive fix or can i do it myself??

 

Sounds like a bad brake switch to me.
