faulty brake lights on 1994 Lexus LS400

my brake lights come on periodically over thjthe past month even when the car is turned off and no one is in it. I have been driving away in another vehicle and looked back and the brake lights were on. I opened the car and pressed the brakes and they went off. Strange!!!

a simple test will see if the brake light switch intermittently sticks. actually, a fairly common problem on older cars.
