I knew I'd have more information to put in, but I couldn't think of it at the time.
First off, the dual-lighting simple means the Motor controllers light green and red at the same time, so it looks a bit orange.

Anyway, our signal light is currently not operational, but that's an unrelated issue. The light on the digital sidecar seems fine, though. I don't think it indicated any issue, but I could be wrong, I just don't remember.
The driver station indicates communication and code as normal, and we were able to re-deploy code onto the robot, but it moving the joysticks didn't control it.
The issue is persistent.
We did not test the solenoids individually, so I cannot say they caused any change in signal.

The camera itself remained operational, there was no issue retrieving images from it. Only the ring of LED lights was disabled.

Any more questions or ideas?
