PROBLEM TO BE SOLVED: To provide vehicle-mounted load control device, vehicle-mounted headlight device and vehicle-mounted taillight device allowing miniaturization of relays/fuse boxes and prevention of simultaneous inability of the use of a plurality of loads. SOLUTION: This vehicle-mounted load control device 1 is provided with a power supply terminal 2 connected to a power supply line S1 via the fuse H9, a load connection section 3 connected with load constituted of a vehicle-mounted light source L, a switch section 5 provided in a form corresponding to the load connection section 3 to control a power feeding state from the power supply line S1 connected to a power supply terminal 2 to the light source L connected to the load connection section 3, and a control part 6 for controlling the switch section 5 based on an inputted control signal. A plurality of load connection sections 3 connected with a plurality of light sources L having different uses are electrically connected to the power supply terminal 2. When the size of current flowing in the light source L connected to the corresponding load connection section 3 becomes a prescribed value or more, the switch section 5 stops power feeding from the power supply line S1 to the light sources L.
