When I turn on my truck lights the rear driver side light is on but when I turn the lights off and press the brakes, the rear driver side light is not on. Is there another bulb I can't see that needs replaced or is there something else wrong?

The tail lights and brake lights are 2 different circuits and the bulb has 2 different filaments so it's likely a bad bulb.

Check the bulb, it is a dual element.
