It's just a Lamp that does all the work for you, okay, except one small thing. You have to place it, and that's it. On sunset, the light goes on, and off at sunrise. No AG's, no switch, i would say "place and forget Lamps".
If someone wants to place it in his/her craft, do whatever you want, i don't care about "the points". You only need the part called "this one", no chip or other things.
For those players that only interested in how it works, it's an fuel tank with added input controller and light. It's always activated, the input controller is only for the brightness. That means that you only have to change the input to, for example, Slider 4 (and maybe delete the curve/axis values (-1,1)) and you have a light with adjustable brightness, and adjustable shape. Saved as subassembly and you always have the right lamp. Or as the adverts would say, this is the last lamp you'll ever download.
Have fun

Fuel Tanks, not engines.
The light part has the name "this one" i think.
I'm looking ingame and edit this post if I'm wrong.
