My boyfriend recently replaced one of the brake lights on my 2002 Galant. Today we noticed that when the brakes are applied the parking lights come on and the dashboard and stereo lights flicker. Could these problems be connected or should we look at possible fuse or wiring problems?

They two are coincidence at best. The likely problem is a bad ground at one of the rear taillights. What is probably happening is the brake lights are using the park lights power feed as a ground source which will cause all kinds of problems. I would bet that if you had the lights on and applied the brakes either the park lights would turn off, everything would turn off, or the lights would get dim. The bad ground could be a corroded socket, a bad bulb or a broken wire. It will take a little digging to find out which one it is.
