desired light distribution performance becomes obtainable from the lamp since the surface configuration of the reflective surface element 12s is also formed like a horse saddle the luminous portion b appearing luminous in the reflective surface element 12s as the viewpoint moves is moved in a different direction when the lamp observing angle is changed from the elevational view of the lamp and the appearance becomes full of variety when the lamp observing angle is changed to ensure that design novelty is secured as the vehicle lamp is arranged so that light from the light source bulb is diffusion reflected forward in both vertical and horizontal directions according to this embodiment of the invention the desired light distribution is easily obtainable from the lamp with neat appearance when it is seen from the outside the aforesaid design novelty can be expressed on the basis of a regulated pattern such as a grid pattern according to this embodiment of the invention a second embodiment of the present invention will subsequently be described fig6 is a side sectional view of a vehicle lamp according to this embodiment of the invention fig7 a sectional view taken along an arrow vii of fig6 illustrating a single article of the vehicle lamp and fig8 an enlarged perspective view of a portion viii of fig7 a lamp 30 according to this embodiment of the invention is a circular marker lamp in elevational view and the inner surface 32a of a lamp body 32 is a paraboloid of revolution p with an axis ax extending in the longitudinal direction of a vehicle body as its center axis so that light.
