Re: Brake light on. Codes?

I am beginning to think it is the brake switch. I was driving one day in traffic and the light in the corner started to blink. I counted 10 blinks and then pause, 10 blink pause, etc. I turned off truck started up again and then light came on steady again after 35mph. It hasn't blinked again. I was also wondering if the brake light comes on if your brake pads are wearing low? Do these trucks have a sensor to detect brake wear?
