The invention discloses an LED lamp for an electric car. The LED lamp comprises an LED lampshade, a rear shade, a base, a spotlight shade and a cooling fan, wherein the rear shade is arranged on the outer wall of one side of the LED lampshade. An electric plate is arranged in the middle position in the LED lampshade, and a distance head lamp and a dipped head lamp are arranged on the electric plate. The base is arranged on the end face of the bottom of the rear shade through a connecting plate, and sealing chambers are formed in the LED lampshade and the rear shade. A drainage exit is arranged on one side of the spotlight shade, and the LED lampshade and the rear shade are aluminum alloy components. The cooling fan is arranged in the LED lamp, so that the heat generated by the LED lamp during working can be emitted through the cooling fan in time. Therefore, the inner parts are not easy to age after being used for a long time, and the service life of the LED lamp is prolonged to a certain extent.
