Description & Operation: Description

The twilight sentinel system automatically controls on-off operation of headlights, taillights, and instrument panel lights in response to ambient light intensity. A time delay control allows lights to remain on for a pre-selected period after ignition is turned off.

The system operates independently of the headlight switch. On models equipped with Daytime Running Lights (DRL), the twilight sentinel system controls both systems automatically. Twilight sentinel system operates when headlight switch is in OFF position, but ignition and twilight sentinel switches must be in ON position. Headlight switch operates exterior lights independently of twilight sentinel system.
