Lighting device for a vehicle light (1) comprising at least one light source (2), at least one light guide (3) with at least three reflection faces arranged in a pyramid such that the incident light falling on the at least one reflection member (31) is dispersed substantially in at least three different directions, in which a second reflection face (311b) and a third reflection face (311c) are designed to reflect, inside the light guide (3), the light towards a second reflection surface (32) and towards a third reflection surface (33) that is designed to reflect the incident light internally towards a surface (4) to be illuminated. This provides a simple day running light function using a minimum number of components while retaining high uniformity and efficiency.
