Abstract
A vehicle headlamp includes right and left reflectors disposed in a lamp body and a ballast that allows a discharge bulb mounted in the reflector to continue a stable discharge. The pair of right and left reflectors is offset in the vertical direction. The right reflector is also offset in the fore-and-aft direction to be located behind the adjacent left reflector. The ballast is disposed to extend over enlarged spaces extending from below the right reflector. Thus, the center of gravity of the ballast is made close to the center of gravity of the headlamp excluding the ballast.
