Abstract
A roadway lane marker has a translucent body to receive light from a vehicle's headlights on its back window, the light being transmitted through the marker body to illuminate its front face. A plurality of such markers, implanted at spaced intervals along edges of roadway lanes, will delineate to a driver looking back from a vehicle entering a roadway at night from a merging side road or ramp, the lane in which a vehicle generally behind him is approaching.
