Twilight Sentinel Lighting System

This lighting system will automatically turn on headlights when ambient lighting (daylight) is reduced to point at which headlights are necessary. This is accomplished through use of a photocell mounted in defroster grille. System will operate with headlight switch in OFF position, ignition on and twilight sentinel switch in ON position. This lighting system can also be pre-set to remain on for up to 3 minutes after ignition is turned off. Although this system operates through original headlight switch circuits, it operates independently of headlight switch. Headlight switch operates exterior lighting system independently of twilight sentinel system.
