Trying to find some rope lights that I can cut every inch or so

I bought some that I thought would work but they ended being waaay thinner than I thought. I'm looking for something that's about a centimeter wide and can be cut every inch, and without that dotted light look. Something flat would be best since I'm trying to put this on foam

Images in order:

- Part I'm working on

- Right thickness but can only cut every 2 inches and lights are too far apart

- Solid light strip that can be cut every centimeter but way too thin

- Comparison between the two
