    摘要： An automotive lamp includes an LED and a light guide (20). The light guide (20) has the light, emitted from the LED, enter through an incident surface (20a) and emits the light frontward from an emission surface (20b) by guiding the light inside the light guide (20). The light guide (20) includes a plurality of steps (24) on a rear face (20c) side of the peripheral surface of the light guide (20). With the plurality of steps (24), the light traveling inside the light guide (20) is reflected toward the emission surface (20b). The pitch (P) between each of the plurality of steps (24) is set to 0.5 mm or below.

    摘要： A first lens cover (22A) of a first lamp unit (20A) includes a first light control surface (41A) that is formed to be continuous with a first emission surface (35A) and that emits light (L1) from a first light source (23A) forward of the lamp. A second lens cover (22B) of a second lamp unit (20B) includes a second light control surface (41B) that is formed to be continuous with a second emission surface (35B) and that emits light (L2) from a second light source (23B) forward of the lamp. The first light control surface (41A) and the second light control surface (41B) are disposed continuous with each other with a gap G therebetween. The first light control surface (41A) extends farther than a first connection portion (36A) in a direction toward the second light control surface (41B). The second light control surface (41B) extends farther than a second connection portion (36B) in a direction toward the first light control surface (41A).
