Abstract
A vehicle indicator lamp includes a reflector having a diffusing and reflecting function that increases the lamp fixture efficiency by eliminating the loss of reflected light. The structure includes a reflector having a reflective surface which diffuses and reflects light forward from a light-source bulb arranged in a lamp fixture reference axis Ax, and a transparent lens in front of the reflector . The reflective surface is formed such that the inner peripheral edge region thereof radiates reflected light in a direction substantially parallel to the lamp fixture reference axis Ax, while the outer peripheral edge region thereof radiates reflected light in a direction near the light fixture reference axis Ax. Consequently, the diffused and reflected light from the reflected surface is not blocked by either the light-source bulb or the standing wall of the reflective surface outer peripheral edge, thereby substantially eliminating the loss of reflected light.
