Embodiments of the present disclosure relate to roadway delineators with one or more light sources that provide illumination and increased visibility. In one implementation, the delineator is operable between a stowed configuration and a deployed configuration. The delineator may include a plurality of panels with flexible connections that connect the panels to one another and allow the delineator to be collapsed. In addition, the delineator may be self-powered and include a solar array and/or a rechargeable power source for the one or more light sources.
