Frank, as Jim indicates, the entire pillar light is held in by large clips and prys out. The plastic cover is non-removable. Take it easy prying them out...little from the top, little from the bottom. The clips can break off and then the light will need to be replaced. I have both nice used and NOS on my list. Good luck and let us know your success! PS: wiring in there can be brittle so be carefull when wiggling them around don't scrape off any cloth insulation leaving bare wires that can short out or cause a fire.
