Just a big WOW!!! That ship all lit up is wild!! I might consider a pot to bring the lights down, then again, it just might be the camera, night with bright lights is hard to photograph, another method is making a voltage divider. They are an effective way of dropping voltage and having full voltage on the same circuit. This simple circuit shows how the larger resistance resistor drop 3.3volts from the circuit, but if the LED needed 5 volts, you could still get it by going from ground to the 5V input. The 3.3Volts would not be felt by the circuit. Using Resistors of equal value, you get equal voltage drops, so a 12 or 24Vcc system could really be cut up and be used to wired all kinds of stuff, and all kinds of voltage levels.
