Abstract
A control system for daytime running lights (DRLs) is provided that includes a controller for controlling DRLs according to whether the ignition switch is ON and information from the dimmer switch signal of a combination switch, and a plurality of switches that undergo switching according to signals of the controller. Accordingly, if the combination switch is set to activate the DRL system when the ignition switch is ON, a closed loop is formed with both headlights, and the current available to each headlight from the battery is reduced to one half of what it would be if loops were made independently for each of the headlights. When the dimmer switch is selected to high beam, a separate loop is made for each headlight so that a normal amount of current is available to the headlights.
