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 14 having a reflective surface 14a which diffuses and reflects light forward from a light-source bulb 12 arranged in a lamp fixture reference axis Ax, and a transparent lens 16 in front of the reflector 14. The reflective surface 14a is formed such that the inner peripheral edge region 14a1 thereof radiates reflected light in a direction substantially parallel to the lamp fixture reference axis Ax, while the outer peripheral edge region 14a2 thereof radiates reflected light in a direction near the light fixture reference axis Ax. Consequently, the diffused and reflected light from the reflected surface 14a is not blocked by either the light-source bulb 12 or the standing wall 14c of the reflective surface outer peripheral edge, thereby substantially eliminating the loss of reflected light.
