I was wondering if anybody has had the same problem that I have. On my '91 K1500, my parking brake light seems to flash randomly, except for when the parking brake is applied. The guy I had bought the truck from in November, said that it was the parking brake sensor. But when I went to a dealership to get a new one, they didn't know anything about a parking brake sensor. Also, if I disconect and then reconnect the battery, the light wont flash, it will just stay on, then a week or so later, start flashing again.
