TT mods

Just got back from Lowes looking at tile for home remod project. While there I came across the peel and stick backsplash tile and my DW was like we should do that in our trailer. Our immediately went to RV.net and showed here some of the back splashes that members did. This mod is a go, now what I'd like to know is if anyone out there has replaced their under the cabinet pancake light with an led light fixture? If so what kind and where did you get it? Now that the DW is all hyped up, I want to take advantage of the situation. Thanks for any help you can give and remember, there is no substitute for experience.
