While attending the Washington (state) Get-Together, I saw a Casita that had a light in the refrigerator that looked great. I found out that a Casita owner, "cagal," had worked out how to install a LED light in the refrigerator and it became a big hit with many Casita owners.
I ordered the $20 light kit from cagal. It's a very complete kit and simple to install. The only change I had to make was to lengthen the wires by about 10 inches. This was due to the Casita's refrigerator temp sensor opening is on the right side of the refrig while it is on the left side in my 19' Escape. I followed the advice of another Casita owner, in the link below, and used a camera to verify the location of the switch and that, indeed, the light goes out when the door is closed.
Here is the link on the Casita forum about the light:
If you have an interest in lighting up your Escape refrigerator, this kit is hard to beat. Just go www.casitaforum.com
and send cagal a private message. Tell her that this is for an Escape and she will make the wires longer.
