Ceiling Lights for 2007 Itasca Navion

The product is a incandescent ceiling light fixture containing two bulbs with translucent lens designed for indoor use in areas like the bathroom, kitchen, or bedroom of a 2007 Itasca Navion RV. The light is operated by a wall switch and runs off of shoreline or DC. These lights are hard to find as, from what I've been told, Winnebago does not manufacture them now. The fixture measures: 4-5/8" wide x 12-1/2" long. I have three units with lens and one unit without lens.
