Daytime Running Light (DRL) - A high intensity amber light, always on when the car is running and the headlights are off. The DRL is automatically cancelled during turn signal operation.
Park - A reduced intensity (1/7 the light intensity of the DRL) amber light. Active when the headlights are on.
Turn Indicator - A high intensity amber light that flashes with the vehicle's turn signal system.
"No fabrication is required for installation. The four-wire electrical connections could not be easier: ground, park light, turn signal, key-on power."
