Here's a link to the lights that aren't submersible. http://www.rvtoyoutlet.com/mm5/merchant.mvc?Screen=PROD&Store_Code=RV&Produc... If I had guides on the trailer I could mount the lights on those (but I don't, and they'd need to be metal for the magnets.) I guess they could go on the trailer and I could remove them every time I backed it into the water but odds are I'd forget pretty soon and ruin expensive lights. Bobbie
