Install a Pacific Insight Automatic Headlight Control module in your vehicle and never touch your headlight switch again.  Our "smart" Automatic Headlight Control modules turn your headlights on for you at reduced intensity in the daytime and at full intensity at night or in times of low ambient light levels.  They also turn them off for you, with an adjustable time-off delay from 0 to 90 seconds.
