Hi there. Check all of the wiring from the headlight switch to the headlights and the turn signal switch to the turn signal lights. See if there is a short causing the lights to exceed the power limits causing the engine ground or ignition power to divert through the lights. If you need further assistance with your electrical issues, then seek out a professional, such as one from Your Mechanic, to help you.
