Good to here from you. Pretty much any of the stip lights available are interchangable. Just make sure they are white as they make several colors. They all come from the same Chinese sources.
Just go to amazon and search led self adhesive strip lights.
If you o to the Hella web page you can find the light for the ceiling there. Part number 2JA 980 596-031.
We also bought some chinese knock offs that work but I don't think they are the quality of the Hella.
