The invention discloses a side steering lamp and side marker lamp same light source control circuit which comprises a side marker lamp signal input end and a steering lamp signal input end, the side marker lamp signal input end is divided into two paths, one path is connected with a light-emitting diode, the light-emitting diode is connected with a collector electrode of a first triode and a collector electrode of a second triode, and the other path is connected with a steering lamp signal input end. The emitter of the first triode and the emitter of the second triode are grounded, the two paths are connected with a first resistor and then are respectively connected with the base of the first triode and the collector of the third triode, and the emitter of the third triode is grounded; the signal input end of the steering lamp is divided into three paths, one path is connected with a light-emitting diode, two paths are connected with a second resistor and then are connected with a base electrode of a second triode, three paths are connected with a first diode and then are connected with a second resistor, the second resistor is respectively connected with a third resistor and a first capacitor, the first capacitor is grounded, and the third resistor is connected with a base electrode of a third triode. According to the control circuit, when the side steering lamp and the side marker lamp share the same light source, the side steering lamp is driven preferentially.
