Abstract
A vehicle headlamp having a clear front lens, light bulb and a shade that covers a front portion of the light bulb, in which the shade has an octagonal cylindrical portion, and slits extending in the axial direction of the cylindrical portion are formed in the ridges formed by adjacent flat surfaces that constitute the octagonal cylindrical shape of the cylindrical portion, thus allowing heat generated by the light bulb to be released out of the shade, preventing a glare light.
