Automatic Operation

Twilight Sentinel system will operate automatically when the ignition switch is on, the headlight switch is off and the controlling pointer is turned on (any position on the dial counterclockwise from "OFF" position). The system will automatically turn lights on at dusk.

At daybreak, system will turn the lights off. The system is designed so lights will not go on or off when there are sudden changes in lighting such as going through tunnels, passing under bright lights, etc. This is accomplished by a 10-60 second delay before amplifier switches system either on or off.

A variable time-delay switch control permits the driver to select a delay period before headlights turn off. This can be a few seconds to a maximum of 4 1/2 minutes after ignition switch is turned off. Additional lighting may be provided (during this period) by turning on cornering lights (if equipped). All lights will turn off automatically at end of time-delay period selected by driver.
