Improved windshield wiper light circuitry for a device that automatically turns on vehicle head lights and other lights whenever the wipers are on is provided. A double-pole, single-throw relay switch (1) is positioned in vehicle circuitry between the ignition switch (13) and the light switch (14). One of the two poles has as electrical lead (3) to the low-beam head lights and the other (4) to the rear lights, park lights and side lights together. A diode rectifier (12) is provided in circuitry between a line (9) for continuous operation and a line (7) for intermittent operation of a wiper motor (11). A light shut-off delay provided by use of a timer (17) acts as a safety sentry light for a period after the ignition switch (13) is deactivated. A single pole relay switch (19) enables this circuitry to operation any 12-volt windshield wiper system.
