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.

    本发明公开了一种侧转向灯与侧标志灯同光源控制电路,包括侧标志灯信号输入端和转向灯信号输入端,侧标志灯信号输入端分成两路,一路连接发光二极管,发光二极管分别连接第一三极管的集电极和第二三极管的集电极,第一三极管和第二三极管的发射极均接地,二路连接第一电阻后分别连接第一三极管的基极以及第三三极管的集电极,第三三极管的发射极接地;转向灯信号输入端分成三路,一路连接发光二极管,二路连接第二电阻后连接第二三极管的基极,三路连接第一二极管后连接有第二电阻,第二电阻分别连接有第三电阻和第一电容,第一电容接地,第三电阻连接第三三极管的基极。这种控制电路在侧转向灯与侧标志灯同光源时,侧转向灯优先驱动。
