Below is a rough schematic of the lighting system for a streetcar powered by a 120 VDC supply. How can I arrange the wires inside the trolley for the interior lights (1-16), headlights (19-20), doors (21-24), and platform lights (17-18), ensuring that each has its own switch?
Does the electrical system require additional safety components? What type of cable can be used for wiring these lights?
