Brake lights

Need some help.. my 06 f350 6.0 for some reason after driving for a while my brake lights go dim? Not sure what it could be. Also, I noticed my brake lights haven’t been shutting off after I shut it off. Anyone?
thanks

Mine is a 2004.5 aftermarket unit so it might be a little different.. That was my problem. New unit solved it. I did just disconnected to diagnose.

Did you unplug both plugs (assuming it's after market like mine)
IIRC 2005 or six the unit is supplied factory. Mine was an add on. Power supply comes from same plug under dash. That is where I'd start.
