The invention discloses a state monitor of vehicle stop lamps. The monitor comprises a direct-current power supply, first and eighth resistors, a first diode, a second diode, a first stop lamp, a second stop lamp, double light-emitting diodes, a first operational amplifier, a second operational amplifier and a switch. The two operational amplifiers are formed to a voltage comparer; a reference voltage is obtained from partial pressures of the third to sixth resistors; when the stop lamps are not damaged, the double light-emitting diodes emit no light, and the stop lamps are normal; and in a similar way, if the double light-emitting diodes emit light, the stop lamps are broken down. Compared with the prior art, the monitor has the advantages of simple circuit structure, few electronic elements and low cost; and in particular, the monitor can monitor the state of the vehicle stop lamps, can timely to prompt drivers when the stop lamps are broken down to effectively prevent the potential safety hazard, and has the promotion and application values.
