Lamp Failure Indicator/Sensor keeps burning out on 1989 CAMRY Please Help!

[JOET/CAMRY]

Hello, My 89 camry keeps eating up the lamp failure sensors like crazy. When I start my car then hit the brake pedel the indicator light on the dash comes on telling me there's a burned out bulb in the rear of car ; but the bulbs seem fine. the brake lights stop working. Have replaced this part 3 times in the last 6 months getting a used one from the junkyard. Does anyone know why this part keeps dying on me? Thanks. Joe.

Check your bulbs ( brake/running lights) remove them and if you have a multimeter check the contacts on the bulb to see if they are shorted together internally. That is what I found wrong with one of my bulbs.
I had a simular problem, when I pressed my brakes ( with out the parking lights on )both the brake light and the running light elliments would come on at the same time, sending voltage back to the light failure sensor and heating up the circuit board and burning the trace between the brake lights circuit and the running lights circuit.
