Headlamp flasher
The headlamp "flasher" can be activated whatever the positions of the ignition switch and the light switch by using the dipswitch (215) to the right of the steering wheel.
When the dipswitch (215) is moved to its "spring-loaded" position, the main-beam lamps will be powered with +30 which goes via the filament monitor (228b) and the fuses (10 and 12) to the main-beam lamps (11 FL and 11FR)
The MIU (540) receives power from fuse 10 so that a lamp on the MIU lights up to indicate that the main beam is on.
