Abstract
A vehicle headlamp using a high-power LED light source, receiving power regulated by a driver circuit, is mounted in a housing and covered at least in part by a light transmissive cover using a construction by which heat developed by the driver circuit (current regulator) is conducted to the light transmissive cover, thereby heating the transparent cover and so retarding the formation or accumulation of ice and snow on the light transmissive cover.
