parking brake light

last night i parked my truck as usual and this morning the light for the parking brake stayed on as well as my let turn signal. i know the left turn signal has been doing that for a while and it turns off on its own or at least dims down. the thing is i did not turn on the brakes last night. what can i do to fix it or is their something else.

Check the condition of the individual light sockets. If they get corroded they can short to ground and cause all sorts of weird issues.

Attention !!!!!!!!!!!!!!

CHECK ALL OF YOUR BRAKES !!! You may have a bad wheel cylinder and you may loose your brakes. Mine came on after working the brakes all over and the first time it came on the wheel cylinder went bad the second was a fitting that wasnt tightened enough.
