Check the listing for details. Dakota Digital PAC-1300 Retained Accessory Power, Light Control. Condition: New. Listed at 251.99 USD. Combining three very popular functions, the new Dakota Digital PAC-1300 offers automatic headlight control, dome light control, and retained accessory power! Similar to some features found in several new production vehicles, the PAC-1300 will activate the vehicle’s headlights in low ambient light conditions and turn off the headlights as those conditions are increased to a safe level. This new revolutionary unit will leave the headlights on for a user-selectable time as the vehicle is exited to safely light your path. The PAC-1300 also contains a user-selectable time delay on the dome light after closing a door or turning off the key. Instead of abruptly turning on and off, the PAC-1300 adds a smooth fade on and off operation to your existing dome light.
