Abstract
A plug in circuit component is provided for switching headlights of vehicles such as automobiles between two positions; full beam and half beam. When the headlight is switched from low to high beam, the low beam disappears in conventional systems, however with the present invention the low beam remains illuminated even when the high beam setting is on and this is accomplished preferably by the use of a diode in the device.
