This year, our team used LED lights to:
- indicate whether the target is to the left, to the right or just right. This is so that the drivers don't have to look at the laptop screen for the video stream.
- indicate the shooter speed is within tolerance of the target speed, so the drivers can shoot consistently.
- indicate various teleop modes (e.g. fully automatic, semi automatic and full manual).

Our LED lights strips are connected to the solenoid module and we have written a generic light control module that allows the caller to either turn the light solid ON or OFF, or specifies any blinking patterns (e.g. 3 long blinks, 2 short blinks and repeat the pattern etc.). The module even supports RGB so it can specify what color combinations in the blinking pattern. In theory, we could even do pulse width modulation on the RGB lights to get many colors but we haven't tested if it actually works.
