To perfectly realize a harmony between a head lamp and a clearance lamp by providing the clearance lamp adjacent to the head lamp at aright corner part of a vehicle body front end as a combination lamp with this head lamp, in which a reflection beam necessary for distributing light without any thermal distortion in a clearance lamp body is obtained.

A reflector 28 made of an iron plate whose surface is treated with aluminum vapor deposition is mounted on a part constituting a clearance lamp lighting chamber 20 in a lamp body 16 in such a way as the whole surface of the chamber 20 is almost covered. Accordingly heat radiation caused by a bulb 26 to the lamp body 16 is prevented and then a reflection beam necessary for distributing light is secured and besides the clearance lamp 10 has the same luster as the reflector 50 of the head lamp 12 when the clearance lamp 10 is observed in appearance during non-lighting.
