Claim:
A vehicular lamp comprising a lamp chamber formed by a lamp body having a front opening and a transparent front cover attached to the front opening of the lamp body, and a lamp unit provided in the lamp chamber so that an optical axis direction of the lamp unit is adjustable with use of a tilting movement adjustment mechanism; wherein the lamp chamber is provided therein with a millimeter wave radar device that emits a millimeter wave signal and detects at least a separation distance and a relative velocity with respect to an object based on a reflection wave signal from the object that has reflected the emitted millimeter wave signal; the millimeter wave radar device is comprise of an antenna unit and a controlling unit that are provided separately from each other, the antenna unit transmitting the millimeter wave signal and receiving the reflection wave signal resulting from the emitted millimeter wave signal, and the controlling unit controlling operations to transmit and receive the millimeter wave signal performed by the antenna unit so as to detect, based on the reflection wave signal received by the antenna unit, at least the separation distance and the relative velocity with respect to the object that has reflected the millimeter wave signal; and the controlling unit of the millimeter wave radar device is attached to the lamp body, and the antenna unit is attached to the lamp unit.
