yes i have.had the mrs. hit the brakes...it lights up the parking light filament;and when you hit the brakes with the parking lights on the bulb goes out until you let off the brake.i double checked to make sure nothing in the socket was touching each other.i went to the u pull it yard and got another socket.i unplugged the whole lamp housing and stuck the three wires from the used socket into the corresponding holes for the ground,brake,and parking light and works properly;so i'm guessing something is going on inside the socket i can't see.thanks everyone for the replies.
