Operation
On cars for the CA market, the headlamp dipped beams also serve as daylight driving lights. The lights will be switched on when the ignition switch is in the drive position and the light switch is set to 0 or 1. The parking lights, rear lights, number plate illumination and side marker lights will also be alight.

When ignition switch 20 is in the drive position and light switch 10 is in position 0 or 1, terminal 87A of relay 174 will supply dipped beam filaments 12 across fuses 16 and 17.

When the light switch is in position 2, relay 174 will be energized from terminal 56 of light switch 10. The relay will be energized, thus switching out the daylight driving lights, in order to avoid reverse currents.

Fault-tracing hints
The daylight driving lights will be operative when ignition switch 20 is in the drive position and light switch 10 is in position 0 or 1.

1. Check fuses 16 and 17 (dipped beams) and check that the supply to them is live.
2. Check the bulbs and check that the supply to them is live. Check the earthing.
3. Check light switch 10 and relay 174.
4. Check the connectors, cable harnesses and earth connections.
