PROBLEM TO BE SOLVED: To provide a lamp body controller capable of maintaining a hazard indication state of a lamp body even when a main switch of a vehicle is turned off.SOLUTION: A lamp body controller includes: a second resistor (a load detecting resistor 2) connected in parallel with a first resistor (a load detecting resistor 1); and a second control circuit (IC2) to which a second voltage drop signal obtained by voltage-dividing a first voltage drop signal with the second resistor is input. A second control circuit includes: a second load detecting portion (a load detecting portion 50b) detecting, based on the second voltage drop signal, that an indication state of a lamp body (a turn signal lamp 15a, a turn signal lamp 15b) designated by turning on an indication switch (a switch unit 23) is in a lighting period; and a second driving part (a driving portion 60b) for outputting a drive signal maintaining a conduction state of a switching element 24 according to a determined result of comparison between a detection result of the second load detecting portion and a voltage level which is set so as to correspond to the indication state during the lighting period of the lamp body. |
