Abstract: A road marker apparatus, system and lighting module and corresponding methods of manufacture, installation and replacement. There is a road insert having upwardly facing ridges and an internal cavity with interior surface textures and a tapered front cavity; a boot of incompressible material disposed within the internal cavity of the road insert and form-fit thereto; and a housing body removably disposed within the boot cavity and form-fit thereto. An array of exterior surface textures that operate as a forward operating taper lock between the housing body and the road insert that restricts forward movement and rotation of the housing body with respect to the road insert; and a housing cavity within which one or more physical modules may be disposed. There is a rear lock behind the housing body that prevents rearward displacement of the housing body with respect to the road insert.
