A lamp body control apparatus controls, in accordance with an operation of a display switch that is provided on a vehicle, blinking of a lamp body that is provided on the vehicle. The lamp body control apparatus includes: an output part that outputs a blinking signal which blinks the lamp body to the lamp body from a drive output terminal based on a blinking command signal that commands a blinking timing of the lamp body; an input part that outputs a status signal of a first logic which indicates that a state of the display switch is in an ON state when a signal level from the drive output terminal is a first level and that outputs a status signal of a second logic which indicates that a state of the display switch is in an OFF state when the signal level is a second level that is different from the first level; a control part that outputs the blinking command signal to the output part when a logic of the status signal that is output from the input part is the first logic; and a self-maintaining part that maintains a logic of the status signal based on a logic of the blinking command signal when the lamp body is in a blinking state.
