Abstract: A housing of an example of an electronic apparatus has a top surface and a bottom surface and has a flat shape. A power supply section having a flat shape is a power supply section, which is a housing case capable of accommodating a battery or is a battery, and the power supply section is provided at a position inside the housing that intersects with a reference plane perpendicular to the up-down direction. A first substrate is provided parallel to the reference plane on the top surface side relative to the power supply section. A second substrate is provided parallel to the reference plane on the bottom surface side relative to the power supply section. The electronic apparatus includes at least one of a vibrator and a speaker at a position that intersects with the reference plane.

Abstract: If an ignition switch of a vehicle is ON and the vehicle speed is not zero (i.e., the vehicle is travelling), the lighting of a work lamp is prohibited even if the work lamp operating switch has been set to ON. This ensures that a work lamp does not remain lit by mistake while the vehicle is travelling, and that battery consumption by unnecessary lighting of a work lamp is minimized.
