We have a 78/79 Argosy Minuet and the light fixtures were all funky. All discontinued. So we contacted Andy at Inland RV and they were all on sale. We lucked out!
Round ones were #95283 @ $24.95 each. Vanity/kitchen light #65298 @ $17.95 each.
We found these to be heavy plastic injection molded light covers. They fit perfectly. Just what we needed, and they really brightened up the trailer after having those old discolored ones for so long.
You can go on www.inlandrv.com
website and find out what they have to offer.
