Just went through the same light system exercise with my '66 C10. Replaced headlights, front and rear signal bulbs (1157 amber front and 1157's rear) and had a pigtail wire from Negative post to chassis to clean up connection on. Cleaning the wire Neg. post to chassis connection helped get the best connection and it brighten the bulbs up in my situation. Also discovered that if battery is low it doesn't like that when you're working on those lights.
With my headlights on front parking lights off and front signals still work. With headlights off parking lights on and turn signals still work.
