Abstract: A pair of first guide lights are displayed side by side adjacent to an HUD display area with emitted light from first light sources, and a pair of second guide lights are displayed at the outer sides of the respective first guide lights with emitted light from second light sources. At least one of the number of lighting lights, the lighting cycle, and the lighting order of the first light sources and the second light sources is changed in accordance with a differential value between the current speed and a speed limit set for a road on which the vehicle is traveling.

Abstract: On a combiner, a HUD display area is defined by display light from a projector, and guide lights are displayed. An optical path length from the combiner to a display-light projector, an optical path length from the combiner to a first light source, and an optical path length from the combiner to a second light source in a viewing direction are larger in this order.

Abstract: Emitted light from first light sources cause a pair of first guide lights to be displayed on a combiner side by side at positions adjacent to a HUD display area. Emitted light from second light sources cause a pair of second guide lights to be displayed such that the pair of first guide lights are interposed between the pair of second guide lights. At least one of number of light sources to be lit, lighting cycle, and lighting order of the first and the second light sources is changed in accordance with a current vehicle speed and a change in shift position of a transmission of a vehicle.

Abstract: When a signal indicating that an event involving a need to guide a sight line from an HUD display area to a second display area occurs, a first guide light is displayed, and then a second guide light is displayed.
