The frame includes a bottom having a half-spherical reflector mounted thereon for reflecting image to a middle rear-view mirror in the vehicle and a thickened side formed opposite to the vehicle. At least one chamber is defined in the thickened side of the frame and at least one opening is defined in the thickened side of the frame and longitudinally communicating with the at least one chamber. At least one light projector is disposed in the at least one chamber and electrically connected to a reversing system of the vehicle for promoting the bright effect when the vehicle is reversed.
