there will be 2 wires to the front lights, you splice into the line from the turn switch to them, nothing to do with headlights or park lights, the blinkers [and indicators] work regardless of other lighting conditions .... as signals were an option in 54, isn't there provision in the gauge cluster for turn indicators?
