A system of daylight running lights utilizing the front turn signal lights of a vehicle incorporates a solenoid coil and a double pole single throw switch, such that when the coil is activated, both poles are closed. A connection from the ignition circuit to the coil is such that when the ignition circuit is at "run", power is available to said coil. The circuit is such as to prevent the coil from being grounded, thus de-activating the coil, whenever the turn signal switch is on, or whenever the headlight switch is on. When either of these conditions applies, the DPST switch is open. The coil is grounded and thus activated whenever the turn signal switch and the headlight switch are both off. The circuit is such that power can be fed through the DPST switch, when closed, to energize both signal lights simultaneously, thus providing daytime running lights.
