Brake in transmission

FORD brake lights seem to fail more often than those of any other make, and have done so for years, though you see lots of other makes and models also without operating brake lights. With the increase in auto transmissions, we tend to use the brakes more, simply to hold the vehicle stationary at red lights and so on, so brake lights are operating under much tougher conditions than before. They are often in small housings with little or no air flow to cool them, which helps explain why globes fail, but why you should be going through brake-light switches so frequently is a mystery. Have an auto-electrician take a good look at the electrical system. Something else might be causing your problem.
