Abstract: A method of manufacturing a light optical guide, including the following steps: providing the optical guide extending in a main direction, the guide having an outer surface; producing along the outer surface of the optical guide, in the main direction, diffusing or reflecting patterns which can make the light exit the guide; and wherein the diffusing or reflecting patterns are produced by using a laser ray on the outer surface of the optical guide.
