Daylight Driving Lights

US and CA Markets
In the US and CA markets, dipped headlamps are used as daylight driving lights. The lamps go on when the ignition switch is turned to 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 lights switch 10 in position 0 or 1, current is supplied from terminal 87A of relay 174 to dipped beam filaments 12 via filament monitor 228b and fuses 5 and 6.

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

Other Markets
In some of the other markets, dipped head lamps are used as daylight driving lights. The lamps light up when the ignition switch is turned to the Drive position. The parking lights, rear lights and number plate lighting also light up.

When ignition switch 20 is in the Drive position and lights switch 10 in position 0, current is supplied to dipped beam filaments 12 via fuse 31, lights switch 10, filament monitor 228b and fuses 5 and 6.

In certain markets an indicator lamp (47v) is also fitted to show when the lights are on.

Filament Monitor 228b
If any of the main beam or dipped beam filaments fails, the dipped beam relay in the filament monitor operates and terminal C2 is grounded. Since positive current is applied to terminal 9 of pictogram 213 (from the ignition switch), the lighting indicator lamps and the central warning lamp light up. See also the Pictogram-Filament monitor.
