An automatic signal bulb using a power LED is provided to reduce unnecessary consumption of resources by reducing the number of LEDs. A vehicle lamp(100) is installed between a socket(20) and a reflector(30). The socket is connected to a coupling hole(11) formed at a lamp housing(10). The vehicle lamp includes a power LED(110) and a reflection unit(120). The power LED is electrically connected through a power terminal of the socket along the coupling hole of the lamp housing. The reflection unit includes a lens surface(121) and a reflective layer(122). A light flux and a focus of the power LED correspond to the lens surface in order to be reflected at an angle of 10-60 degrees on the lens surface and to be diffused. A parabolic surface or an elliptical surface is formed at a part of an inside of an end of the lens surface.
