We used these on our robot and driver station panel:

You can see a little bit of them working in our reveal video:

It's been brought up that these cheep LED strands use IR, so the are hard to control via the Rio, but we ended up taking the control box and manually wiring in three PWM lines directly to the FETs inside. This lets us use the 5V PWM output to control the intensity of each color individually, and the 12V line just comes from the PDB. I'm working on a write up that I hope to post soon on how to do this, and our team will probably make a custom PCB in the future for it that we'll share with the community.
