Sorry to ask such a dumb question but here goes.
..Sometimes when I park Lucy(52 1/2 ton)the brake light will come on . I installed a new brake light switch. Even put a piece of rubber hose over the switch arm. Today I shimmed the switch hoping to get the darn thing to turn off. The brake lights work fine when I am driving and apply the brakes. After parking the brake light will stay off for a few minutes and then turn on. I would welcome any ideas.
