ABSTRACT:
The present invention relates to a vehicle light control circuit having a microcontroller. The novelty rests in obtaining the information on the different positions of the main light switch by sensing the change in voltage at a predetermined end of each of the sensing resistors of predetermined values connected across the terminals of a number of controlled switches which are inserted in series with the light circuits at physical locations predetermined to be convenient for the installation of the invention on each vehicle. This novelty makes it easy to provide many beneficial operations in turning off with different delays the head lights, park lights, and dome lights, as well as to provide automatic battery protection against any routinely used lights when they are inadvertently left on, without using any confusing additional switches as in prior art.
