The bulb (10) has a rear base (12) connectable to an electric current source, and a front body including a light source for emitting a long range light, and another light source for emitting a short range light based on the selective electrical supply of one of the two light sources. The former light source includes a rear series of LEDs (DP), and the latter light source includes a front series of LEDs (DC). The rear LEDs are arranged in a plane (PP) orthogonal to a general axis (A) of the bulb, and the front LEDs are arranged in a plane (PC) parallel to that the general axis of the bulb. |
