IG2 fuse. When the light control SW is turned to TAIL or HEAD position, current is applied to TERMINAL 6 of the combination
meter through the PANEL fuse.

When the light control SW is in TAIL or HEAD position, the ignition SW turned to OFF from ON position, ignition key is not in
the key cylinder and the driver’s door opened (Door courtesy SW on), the current flows to TERMINAL 4 of the combination

the buzzer in the combination meter goes on to remind the light is lighting up.
