Answer
I don't recall answering you first rquest so I hope I'm not repeating my answer, if you have already tried replacing all the bulbs with the ones from the toyota dealer's parts department, even though the bulbs are working the resistances in them can change and cause problems, also if the center bulb is of the wrong wattage it can cause the warning lite to come on, there is also a tail light failure relay located in the left side of the trunk, remove the carpeting it is mounted on a bracket, just follow the wires to it, try replacing this relay.
