I took a look at your 2007 Four Winds Dutchman Kodiak Motorhome, and while I wasn't able to find out exactly what lights you have, I was able to locate a few similar lights for you to check out.
First, take a look at the:
-Omega RV Double Dome Light with Switch # 328-001-902XPW.
This light is not self-sticking, and will use screws to secure to the roof, however this light measures 11-/38" long, 4-3/4" wide, 1-3/4" deep and is compatible with 12VDC systems. Take a look at the installation... view full answer...
The Replacement Standoff for Stromberg Carlson Exterior RV Ladders # 8531-B comes in a 12" length, but can be cut down to exactly the size you need. You'll just have to push the inner nut (pictured below) further into the tube and then cutting off the excess. Just be careful not to push it too far in because getting it back out can be a challenge. view full answer...
