Has anyone experienced this problem I am having with my 2013 Mazda 3? If your Headlights are on and you apply the Brake, the lights will start blinking like there is a voltage drop. The don't go off, but dim just a bit and brighten, dim and brighten about twice every second while the brake pedal is down. I have even noticed my interior light will do it too, if it happens to be on. I have no idea what the brake light or park lights are doing at this time, because I haven't had anyone follow me yet. The headlights have never gone out, just start blinking. I just bought this car (used) about a month ago and it seems like it has done it since I have owned it. Anyone ever hear of this and what may be causing it?(help)
