Type yor problem for a solution...when I steep on the brakes my dash lights,running lights and radio light all come on

Common problem or complaint, Dash lights out or rear running lights not working. Most common problem for this is the round bulb for the brake and running lights flatten out over time and touch each other inside the bulb holder normally the ends should look like nn but when flattened out look like this _ _ and end up touching and shorting out, replace both bulbs. And on GM cars front running lights can cause the same thing so always check all four running light bulbs(Front and Rear). If it has the turn signal and running lights on the same socket always check this first. G.M. had built into it's wiring system a fail safe that if one running light went out the dash lights will not come on, this is so that you don't get a ticket for a running light or brake light out.
