Introducing, Benji's Light up Command Pods! This mod allows you to turn lights on and off on command pods/modules like you can with cockpits!  It also works on the Hitch-hiker Storage Container. This is good for making your rockets look a lot cooler, as well as being more visible in the dark. This doesn't currently work for the Mobile Processing Lab but I am working on it.
