Yes, you could pull a run directly from a PDP breaker, or wire something off the VRM (and you can add a second VRM if needed for this purpose), or you could even use a solenoid relay from the PCM assuming you're using 12 volt pneumatics and not 24 volt.

Last year on our robot our green LED ring light for autonomous vision processing was powered from the PCM, since our VRM outputs were used by other devices (we had a webcam, and a Raspberry Pi running the webcam and vision processing software, and a D-Link gigabit network switch on board since the OpenMesh radio only has two available ports). This also lets you turn it on and off in software, whereas the VRM output is always on.

As a cheap and easy way to set up LED lights (non addressable, non controllable) we were looking at IKEA DIODER light strips. We would have run these off a PCM relay output or VRM output.
