Fog/Driving Lamp: Description and Operation

FOG LIGHTS
With the Headlight Switch in ",HEAD" or "PARK," voltage is applied to one side of the Fog Light Switch, When the Fog Light Switch is closed, voltage is applied to one side of the Fog Lights Relay Coil, energizing the relay (the other side of the coil is grounded through the Hi Beam Filament of the Headlamps).

When energized, the normally open contacts of the Fog Lights Relay close, allowing voltage to be applied to the Fog Lights.

When the HI Beams are activated, ground is removed to one side of the Fog Lights Relay Coil, de-energizing the relay and turning off the Fog Lights.
