US and CA Markets

In the US and CA markets, dipped beams function as daylight driving lights. The lights go on when the ignition switch is in the Drive position. The car's parking lights, rear lights, number plate lighting and side marker lights also go on.

When ignition switch 20 is in the Drive position and light switch 10 is in position 0 or 1, current is supplied from relay 174, connection 87A, to dipped beam lamps 12 via filament monitor 228B and fuses 5 and 6.

When the light switch is in position 2, relay 174 receives operating current from connection 56 of the light switch. The relay operates and the daylight driving lights are disconnected to avoid reverse currents.

Filament Monitor
If any of the full or dipped beam lamps breaks, the dipped beam relay in the filament monitor operates and connection C2 is grounded. Since connection 9 of pictogram 213 receives positive voltage (from the ignition switch), the indicator lamps for lighting and the central warning lamp light up. See also the Pictogram-Filament monitor.
