A car cigarette lighter with a light indicator includes a power socket and a cigarette lighter. The car cigarette lighter is characterized in attaching an external sleeve to a bottom tube of a handle, and installing a circuit board in electric connection with a circuit of the car cigarette lighter in the external tube. The circuit board has at least one light emitting diode located at a bottom of the transparent handle. A switch in electric connection with the car cigarette lighter is further mounted on the external sleeve. By plugging the car cigarette lighter into the power socket and pushing the handle, the circuit board is conducted, and the light emitting diode is switched on. By the switch of the external sleeve, the electro-thermal winding film is conducted and heated. When the winding film is heated to a high temperature, the clip in the tube of the power socket releases the internal cap of the internal tube, such that the internal tube of the car cigarette is pushed outward to form an open circuit, such that the light emitting diode is switched off. Therefore, the light emitting diode provides the inspection, indication and illumination effects.
