Brake light help

The bracket is adjustable, but if replacing the switch I believe the "heavy duty" one has the back to back nuts and might be a little easier to adjust. Drops right in. My brake lights occasionally hung up because the bracket got bent when replacing the master cyclinder and the bracket appears to flex ever so slightly even after bending it back into position. Every time I thought I fixed it, I'd still come out occasionally to a dead battery. Finally installed a little light under the dash to monitior when they were coming on and off. I'd drive for an hour, think it was fixed, only to have it stick on when I got near the house.
