If they can be powered off 5V, then the easiest is to connect them to the VRM, use the 500mA port if it is safe to do so, 2A connection otherwise.

If they are 12V, you can do the same, or wire directly to the PDP as others have said. Don't forget the breaker.

We powered our camera ring light off a solenoid output on the PCM because it can handle 12 volts at up to 500mA. (Note, check if your PCM is set to 12 volts instead of 24 volt output). This way we can turn the light on and off in software.

I bought a set of IKEA DIODER lights hoping to have them installed on the robot - we would just plug them into the PDP - but alas they were too far low on the list of priorities in the pit. Next year!
