Question about 1997 Toyota Tacoma
Your problem is not in the stop light switch.
What you have is a short circuit, or a cross-transference of power.
Your problem will be eliminated by one of the 3 following possibilities:
If you have a trailer hitch wiring harness installed, remove it completely, and see if the problem disapperars; trailer harnesses are notorious for the contacts for the trailer connection getting corroded.
If you do not have a trailer harness, look under the bed, at the wire that feeds the rear taillamp harness, unplug the connector, and look for greenish-blue corrosion inside the connector, this corrosion, if present will also give you thi scondition.
Lastly, look closely at the bulb sockets, and see if there is any corrosion where the bulb plughs in. Corrosion will "backfeed" power, and cause your condition.
One of the above will eliminate your condition.
