LIGHT MODULE FOR A MOTOR VEHICLE COMPRISING A LIGHT GUIDE

The present invention relates to a light module for a motor vehicle comprising: - a light guide (10) composed of an entry face (11) and at least two branches (12, 13) each extending from the entry face according to their own length (L, L') and their own section; - at least one light source disposed at the level of the entry face (11) of the light guide (10), said entry face (11) being adapted to couple the light rays emitted by said light source into the light guide (10); in which the two branches (12, 13) are joined together over a portion (D) of their length from the entry face (11) to a determined separation point (15), the two sections of said branches (12, 13) overlapping over an intersection zone that is present from the entry face (11) to the determined separation point (15) and the two sections being substantially constant along the branches from the entry face (11) over a length greater than or equal to the length of the branches between the entry face (11) and the determined separation point (15).
