I measured the light on the back of our 2003 Itasca Sunflyer. It was an oval light and was broken. The previous owner had used clear caulk and put a piece of plexiglass over the light hole so it lit up but was white. Since I had no idea what size it was, I called Winnebago who told me. I ordered an: American ITC94110 Center Mount Oval Brake Light, Red. It was made by Winnebago Industries and cost a whopping $35.42. It is an LED light. When I installed it, I caulked around it with clear sealant, but it screwed right to the existing mount, I just had to rewire it. No problem for the retired mech. It is $28.40 with about $5 shipping and handling. You can find it on Amazon.
