Description & Operation: Operation

Twilight sentinel system operates automatically when ignition is on, headlights are off, and twilight sentinel system is on. When turned on, twilight sentinel system automatically turns on exterior lights at dusk. At daybreak, twilight sentinel system will turn exterior lights off.

Twilight sentinel system provides a 30-second delay before switching lights on or off, thus preventing system from operating under sudden ambient lighting changes, such as passing through tunnels and exposure to bright lights at night.
