Light Auto Turn Off

With the ignition SW turned ON, the current flows to TERMINAL 7 of the integration relay through GAUGE fuse. Voltage is applied at all times to TERMINAL 11 of the daytime running light relay (Main) through the taillight relay (Coil side), and to TERMINAL 12 of the daytime running light relay (Main) through the HEAD relay (Coil side).

1. NORMAL LIGHTING OPERATION
Turn taillight ON
With light control SW turned to TAIL position, a signal is input into TERMINAL 10 of the daytime running light relay (Main).
Due to this signal, the current flowing to TERMINAL 11 of the daytime running light relay flows to TERMINAL 10 to TERMINAL 3 of the light control SW to TERMINAL 4 to GROUND and taillight relay causes taillight to turn ON.

Turn headlight ON
With light control SW turned to HEAD position, a signal is input into TERMINALS 10 and 13 of the daytime running light relay (Main). Due to this signal, the current flowing to TERMINAL 12 of the daytime running light relay flows to TERMINAL 13 to TERMINAL 13 of the light control SW to TERMINAL 4 to GROUND in the headlight circuit, and causes taillight and HEAD relay to turn on. The taillight circuit is same as above.

2. LIGHT AUTO TURN OFF OPERATION
With lights on and ignition SW turned OFF (Input signal goes to TERMINAL 7 of the integration relay), when door on driver's side is opened (Input signal goes to TERMINAL 6 of the integration relay), the relay operates and the current is cut off which flows from TERMINAL 11 of the daytime running light relay (Main) to TERMINAL 10 in taillight circuit and from TERMINAL 12 to TERMINAL 13 in headlight circuit.
As a result, all lights are turned OFF automatically.
