A work vehicle includes: a vehicle body that travels; a boom attached to the vehicle body to be vertically swingable; a work tool mounted to a front portion of the boom; a first illumination lamp that is disposed in the vehicle body and emits an illumination light forward; a second illumination lamp that is disposed in the boom and emits an illumination light toward the work tool; and an illumination controller that controls the first illumination lamp and the second illumination lamp, the illumination controller executing a lighting restriction of automatically turning off or dimming the first illumination lamp while the second illumination lamp is turned on.

A lighting control apparatus is configured to be applied to a vehicle lamp. The lighting control apparatus includes a first switching converter, a substrate on which the first switching converter is provided, and a first cover. The first switching converter includes a switching element, a coil, and a first output capacitor and is configured to generate a first drive voltage corresponding to a first light source of the vehicle lamp based on a power source voltage. The first cover is formed of a conductive material and covers at least a part of components of the first switching converter in one surface of the substrate. The substrate includes a first conduction part and a second conduction part which are in conductive contact with the first cover. The first switching converter is provided between the first conduction part and the second conduction part. The first output capacitor is provided in a vicinity of one part of the first conduction part and the second conduction part.
