An electronic display includes a light source system and a light guide system, where the light guide system emits light features laterally, i.e., from the side, at selected positions along its length. The light source system includes one or more electronically controllable light sources and further includes optical switches or other arrangements for coupling the light sources to the optical fibers or other light guides of the light guide system. The light source system can sequentially or progressively increase the selected longitudinal position at which the light feature is emitted, resulting in the appearance of movement of the light feature along the length of the light guide system.
