If you're able to determine that it is indeed your brake light switch that's at fault, replacement is simple. In fact, it's likely that you won't even have to get your hands dirty to complete a brake repair of this sort. Remember, there are several different types of brake switches available, including hydraulic brake switches, so be sure to get the one that's right for your specific vehicle. You'll need to know the make, model and year of your vehicle but really that's about all. Your local auto parts store should be able to locate the correct part for you.
