Nice looking tank
One tip for running external lights etc, is magnet wire. It is coated so it is insulated and of course it is very fine. You can run a twisted pair of wires and easily hide them in some small wire insulation so it looks like conduit, just like the prototype
I did this on my Crowmell to hide the wires to the LED in the searchlight. You have to just burn off the insulation with a match on the ends you want to solder.
Cheers
