LEDs on Robot

[apalrd]

There are no rules directly against this, as long as it dosen't interfere with anyone's vision system, or is powered by something other than a 20-amp breaker (directly or indirectly). You can use DIO pins, Relay ports (they're actually 2 digital outputs), or Spikes to drive the lights. We use a few 12v automotive light bars (around 12" long) to indicate important things, and drive them with Spikes. You need 1 spike for 2 channels, although low-amperage lights can be ganged up on a single channel. You would probably have one channel for front and another for rear.
