Cornering lights
CORNERING LIGHTS

  • Turn Signal Activated

    • All the time

    • Night time only

  • Will Stay on until Flasher Turns Signal Light on again

  • Some systems have extra contacts inside turn signal switch

C281 to C283


CORNERING LIGHTS PARKING AND TAILLIGHTS

  • Two Bulb System

    • Relay controlled

  • Three Bulb System

  • Some systems powered through headlight switch and by battery

  • Other systems powered by turn signal switch


Parking lights off turn signal on
Parking lights off / turn signal on

  • Marker light receives power from turn signal switch

  • Ground for side marker through park light filament
