A headlight apparatus configured to irradiate illumination light onto a road surface on which a vehicle travels includes a visible radiation lighting unit and a projector lens. The visible radiation lighting unit generates illumination light. The projector lens is provided on an optical axis of the visible radiation lighting unit, and is configured to distribute and project the illumination light irradiated from the visible radiation lighting unit. The visible radiation lighting unit has an LED, a liquid crystal display panel, and a shutter. The LED emits light. The liquid crystal display panel controls light distribution of the illumination light emitted from the LED. The shutter is provided between the liquid crystal display panel and the projector lens, and is configured to shield the liquid crystal display panel from solar light that enters through the projector lens.

Disclosure herein are systems and methods for dynamically adjusting infrastructure items, such as street lights, construction signage, and/or other lighting elements. The systems and methods may include receiving environmental data for a sector containing the infrastructure items. A quality of infrastructure effectors located within the sector may be determined. A deviation from a standard infrastructure quality associated with the infrastructure effectors may be determined. A setting of the infrastructure items located in the sector may be changed to minimize the deviation from the standard infrastructure quality.
