Abstract

Abstract An illuminated stepping pad is disclosed herein intended to be buried in the ground having a circular base including an upright continuous sidewall terminating in a circular knurled lip. A light is operably carried on said base between a plurality of columns constituting load-bearing standoffs. A lid displaying messages, ornamental graphics or the like is removably carried on the base about the lip and may include an irregular exterior surface of non-skid composition. The lid is composed of translucent material allowing diffusion of the light. Anchor devices may be employed to engage with the ground to prevent undesired movement or rotation of the base.
