Abstract
A lighting device includes a housing including a front opening portion and a rear opening portion; a light source unit including LED light sources and a heat sink configured to absorb and radiate heat produced by the LED light source; a socket formed by an elastic member and configured to allow the heat sink to be fitted and supported in the rear opening portion such that part of the heat sink is exposed rearward through the rear opening portion and that aiming adjustment is enabled by changing a position of the light source unit relative to the housing. A knob used for manually turning an adjustment screw is attached to a rear end portion of the adjustment screw, and the socket is provided with a rib extending along a circumferential direction of the socket and protruding rearward of the heat sink.
