Hi there. Trace all of the wires back to their source. Then check to see what each wire operates. If you are trying to make the radio lights come on with the parking lights, then tie the radio lights into the parking lights. What may have happened is the the lights may have been tied into the brake light switch causing the lights to come on through the switch. This needs to be fixed as the switch could get too hot and stop functioning. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.
