Abstract

The present disclosure discloses an indicator light, and belongs to the technical field of automobile indicator lights. The indicator light comprises a mirror, wherein a protrusion is formed around the edge of the mirror such that the mirror surrounds a cavity with an opened bottom end, the mirror forms at least one paraboloid at a top end of the cavity, and multiple reflection pieces are uniformly arranged on the paraboloid; a lens, wherein the lens covers the mirror and seals the protrusion, and a surface of the lens has etched optical dermatoglyph or electrical discharge machining marks; and at least one light bead, which is arranged in the cavity. The light bead can provide light rays for the mirror and the lens, and its emitted light rays are emitted between the mirror and the lens to increase the utilization ratio of the light rays and improve the light emission uniformity.
