HEADLAMP — Daytime Light System — Operation / Schematic

DRL adds a 'engine-running + switch-OFF' state where low beam + clearance + license + tail come on automatically. Charge warning lamp is reused as the engine-running input (a common Nissan trick — when alternator L pin goes high, DRL knows the engine is turning). Wire colours not legible at thumbnail resolution; wiring captured at topology level only — see flagged uncertain_values.
