The headlamp relay coil (C0282) is provided an ignition feed from fuse 15 of the passenger compartment fuse box (C0580) on a WG wire. The relay coil (C0282) is earthed on a B wire. When the lighting switch is moved to the headlamp position, current flows across the switch (C1082 on LHD, C0041 on RHD) to the headlamp relay switch (C0282) on a U wire. The energised headlamp relay (C0282) provides a feed to the column switch (C1739 on LHD, C1042 on RHD) and the dim dip relay (C0048) on U wires.

NOTE: The feed on the U wire de-energises the dim dip relay.

With the column switch in the dipped beam position, current flows across the switch (C1739 on LHD, C1042 on RHD) to the dim dip relay (C0048) on a UR wire. Current flows across the dim dip relay switch contacts to fuse 22 and fuse 23 of the passenger compartment fuse box (C0581) on a UR wire.

Fuse 22 (C0581) provides a feed to the RH headlamp dipped beam bulb (C0011) on a UB wires. Fuse 23 (C0581) provides a feed to the LH headlamp dipped beam bulb (C0009) on a UK wire. Both bulbs are earthed on B wires.

With the column switch in the main beam position, current flows across the switch (C1739 on LHD, C1042 on RHD) to fuse 24 and fuse 25 of the passenger compartment fuse box (C0581) on a UW wire. Fuse 24 (C0581) provides a feed to the RH headlamp main beam bulb (C0011) on a UO wire. Fuse 25 (C0581) provides a feed to LH headlamp main beam bulb (C0009) on a US wire. Both bulbs are earthed on B wires.

When the column switch is in the main beam position, it also provides a feed to the main beam warning lamp located within the instrument pack (C0233). The warning lamp (C0230) is earthed on a B wire.

Fuse 3 of the under seat fuse box (C0572) provides a constant battery feed to the column switch (C1739 on LHD, C1042 on RHD) on an NP wire. When the column switch is pulled forward against spring pressure, current flows across the column switch (C1739 on LHD, C1042 on RHD) to fuse 24 and fuse 25 of the passenger compartment fuse box (C0581) on a UW wire. Fuse 24 (C0581) provides a feed to the RH headlamp main beam bulb (C0011) on a UO wire. Fuse 25 (C0581) provides a feed to LH headlamp main beam bulb (C0009) on a US wire. Both bulbs are earthed on B wires.

When the column switch is pulled forward against spring pressure, it also provides a feed to the main beam warning lamp located within the instrument pack (C0233). The warning lamp (C0230) is earthed on a B wire.
