Lighting device for a vehicle light in which the lighting device comprises: - at least one light source, - at least one light guide that comprises at least one surface to be illuminated and at least one first reflection member arranged to face the at least one light source such that the at least one beam of light emitted by the at least one light source falls on the at least one first reflection member, - the at least one light guide has at least one third reflection surface and at least one second reflection surface that in turn has at least two regions, in which the at least one third reflection surface and the at least two regions surround the at least one first reflection member, - the at least one first reflection member includes at least three reflection faces arranged in a pyramidal shape such that the incident light falling on the at least one reflection member is dispersed substantially in at least three different directions, o in which a first reflection face is designed to reflect, inside the light guide, the light emitted by the at least one light source towards the at least one third reflection surface, o in which a second reflection face and a third reflection face are designed to reflect, inside the light guide, the light emitted by the at least one light source towards the at least one second reflection surface, - the at least one second reflection surface is designed to reflect, inside the light guide, the incident light towards the at least one third reflection surface, - the at least one third reflection surface is designed to reflect, inside the light guide, the incident light towards the at least one surface to be illuminated, characterised in that it includes - at least three light sources and at least three surfaces to be illuminated, in which the at least one light guide includes at least three first reflection members each including at least three reflection faces arranged in a pyramidal shape, at least three second reflection surfaces and at least three third reflection surfaces that direct the light towards the at least three surfaces to be illuminated, in which the at least three surfaces to be illuminated form a polygon having at least three sides, - and the at least one light guide is a single light guide common to the at least three light sources and connected to the at least three light sources. - at least one light source, - at least one light guide that comprises at least one surface to be illuminated and at least one first reflection member arranged to face the at least one light source such that the at least one beam of light emitted by the at least one light source falls on the at least one first reflection member, -
