1. An automatic moisture sensitive control system for a vehicle having a windshield wiper control system and a headlight control system, said moisture sensitive control system comprising;
- a moisture sensing unit, said moisture sensing unit having a first narrow moisture sensing band and a second narrow moisture sensing band;
said first narrow moisture sensing band of said moisture sensing unit having notches along an upper edge to channel water running down the windshield when said vehicle is not in motion;
an automatic control circuit for controlling said moisture sensing unit and activating said windshield wiper control system and the said headlight control system to begin operation, said control circuit including a first stage circuitry, wherein said first stage circuitry sends control signals to the windshield wiper control system to automatically activate the said vehicle headlight control system.

Abstract
The invention is directed to an automatic system for activating vehicle headlights upon the actuation of a windshield wiper. The windshield wipers automatically begin a wiping cycle when moisture is sensed on a windshield. In the preferred embodiment, a moisture sensing device is strategically placed in the left-hand side of the windshield, at the end of a wiper blade track. When the windshield is no longer wet, the wiping cycle will stop and the headlights will remain on for a short period of time thereafter before turning off.

6. A method for controlling an automatic moisture sensitive control system, including a windshield wiper control system and a headlight control system, comprising the steps of:
-
sensing moisture on a vehicle windshield by a moisture sensing unit; automatically activating a windshield wiper control system controlled by a signal generated from an automatic control circuit upon sensing moisture on the vehicle windshield; automatically activating a headlight control system upon detecting activated windshield wiper control system; automatically disabling said windshield wiper control system and said headlight control system when moisture is no longer sensed on said windshield by said moisture sensitive unit; automatically disabling said automatic control circuit when an operator of said vehicle chooses to manually place windshield wipers in a high speed mode, thereby preventing over-heating of a windshield wiper motor.
