Hi. 2003 Safari 25ss. I decided to replace my old inside lights. The lenses on the old ones would sag down and look loose. I was always pushing them back up. I fussed over many styles and suppliers but the decisions came down to... a) I wanted standard replacement bulbs that I could get anywhere. b) I wanted a base that would cover the old indentation in the headliner. c) I wanted the lenses to be more secure. d) I wanted them to look as good, or better than the originals. With all that I ended up with the Arcon brand, #18123, from RVUpgrades. They also have the matching single fixture, and matching dim-able fixtures I may try. I had a little trouble removing the old fixtures. The old incandescent bulbs heat-welded the headliner to the back of the fixture. A plastic putty knife was used to separate the fixture from the headliner. Well... the new screw holes didn't quite line up. So I made a metal pattern to pilot new holes. I snipped, trimmed, and tinned, the wires in the Airstream and on the new fixture. I’ve heard good things about the Wago 221 series connectors and wanted to try them. They have a little lever-clamp that makes it easy to disconnect and reconnect, if I ever want to play with this fixture again. I was able to get them from Home Depot. I used #6x3/4 truss head stainless screws for the new fixtures, tightened just snug. Used the smaller screws as the old and new holes were so close together. New LED 4000k bulbs.
