Abstract: A safety lighting device for a bicycle including a housing in which is located a self-contained light source which emits light through a lens; the housing also having a plate-like mounting apparatus wedged between pairs of overlapping spokes which allows the housing to be removably secured to the spokes, and further allows the light to be directed radially outwardly to permit ready visibility of the bike and rider while deflecting the light away from the eyes of the rider and any obstructions created by the wheel rim.
