The tape led's are the way to go. There's a huge selection on Amazon.
You can cut it to length and do whatever you want. There are little adapters that go on when you cut it. Small learning curve.
There's good stuff and junk. You want the stuff with 3M automobile sticky on the back, 120 led's per meter, and 5050 led's. The waterproof (IP67) is much thicker and more durable but harder to work with.
It's super cheap and it'll light up the whole world.
