So, on my 08, Wife was pulling it into the driveway last night, the FRONT passenger side parking light was on while she was pressing the brake. release the brake, light goes out.
i have her double check,
all the lights work when the light switch, everything seems to be ok. but this cross feed or something..

again. press brake, front right passenger parking light will illuminate.

i was thinking more the lines of a bad break light switch to let the juice back feed to the front. maybe even the light switch, i'll remove the rear taillight and see what i come up with.

I have seen this before on an old 88 Chevy.  We had some corrosion making contacts in the trailer lights plug on the bumper.
