Abstract
A vehicle headlamp having a clear front lens, a light bulb and a shade that covers a forward portion of the light bulb. The shade is provided with a radiation opening and a shading portion; and the shading portion is formed so as to prevent the light rays emitted from the light bulb from radiating to the front of the light bulb through the radiation opening, thus preventing a glare light and decreasing the temperature of an area around the light bulb.
