PROBLEM TO BE SOLVED: To solve the problem in which, in a conventional vehicular lighting fixture, when the function of a controller is stopped, a light source is extinguished to stop the lamp function. SOLUTION: A vehicular lighting fixture comprises a light source 4, a first load 5, a second load 6, and a controller 7. The light source 4 is connected to a power source 3 equipped on a vehicle. The first load 5 is connected to the light source 4 to adjust the current so that the light intensity becomes the lower limit of the amplitude of the fluctuation of the light intensity of the light source 4. The second load 6 is connected to the light source 4 in parallel to the first load 5 to adjust the current so that the light intensity becomes the upper limit of the amplitude of the fluctuation of the light intensity of the light source 4. The controller 7 is connected to the second load 6 in parallel to the first load 5 to control the fluctuation of the current to be supplied to the second load 6 periodically or non-periodically. As a result, even if at least the function of any one of the second load 6 and the controller 7 as additional components is stopped, the lamp function is maintained to contribute to the traffic safety.
