A light-emitting element driving semiconductor integrated circuit constitutes at least part of a light-emitting element driving device that is configured to drive a first and a second light source when the first light source is not short-circuited and drive the second light source when the first light source is short-circuited and that includes an output capacitor. The light-emitting element driving semiconductor integrated circuit has a controller configured to control the resistance value of a variable resistor connected in series with the first and second light sources according to the voltage across a resistor connected in series with the first and second light sources.
