Brakes lit after you've parked your car? Well, that's probably the brake light switch and it's stuck in its closed position. That won't do. Not only is your car's battery going to get drained eventually, you're also going to confuse drivers following from behind you. If you don't mind getting a ticket-and risking getting rear-ended by unsuspecting drivers-then go right ahead and leave it be. Otherwise, it's time for a little brake light switch DIY right in your own garage. This shouldn't take any longer than an hour, if you're handy with a few basic tools. Now, you may be wondering if it's all right to leave the brake light switch alone if it only sticks momentarily. The thing is, the sheer unpredictability of a faulty switch can bring about equally unpredictable results as well. And when you're on the freeway cruising as usual and an eighteen-wheeler rig tailgates you, that switch better behave. Otherwise, who knows what will happen? It's either it sticks early and the driver thinks you're braking (when you're not) or you brake and the switch fails. Either way, you're screwed and the chances for a grave accident rises exponentially every second. Now, ask yourself again-will you really risk driving with a faulty brake light switch, knowing the possible (and worst) consequences? Besides, DIYing this switch is a piece of cake. It shouldn't take more than an hour of your day. Quality switches are available right here at Car Stuff.
