I HAVE A 98 300 XPLORER 4X4. IT SEEMS LIKE THE BRAKE LIGHT IS ON ALL THE TIME. WHEN THE BRAKES ARE APPLIED THE LIGHT GETS JUST A LITTLE BRIGHTER. SHOULD THE TAIL LIGHT BE ON ALL THE TIME OR JUST WHEN THE HEAD LIGHTS ARE ON? THE TAIL LIGHT IS ON ALL THE TIME.

THANKS!!

Taillight is on anytime the switch is on, even if the motor isn't running, as long as the battery has juice.

 

I'm not a pro .Sounds like a ground problem.Check the light bulb and the socket.

 

Farmr is correct, switch is on light is on.
