PURPOSE:To improve a reflector for auxiliary head lamp to obtain a flux distribution pattern provided with sharp cut lines in parallel with a horizontal line. CONSTITUTION:A first reflecting surface is formed in an upper half part of a reflector 6', and a second reflecting surface is formed in a lower half part thereof. A filament 4 of a light surface bulb is arranged on the center axis of rotation (optical axis) Z1 of the first reflecting surface, and a focus f1 is positioned in the rear thereof. The center axis Z2 of rotation of the second reflecting surface is positioned under the axis Z1 of rotation, and a focus f2 thereof is positioned between the front end 4a and a central part 4b of the filament 4. |
