My take on the Millennium Falcon 10179
Working from Rob's suggestion framework and from the work done by Mark Sandell, I set out to light my 2007 era Millennium Falcon 10179. Instead of 18 cool white PICO LEDs in the engine bay, I used 36, lighting the top and bottom blue lens in each block. I added cool white LEDs for the top and bottom gun turret and one for the cockpit. I also added one to the loading ramp, and adding the magnetic switch to turn it on and off. I did replace the head lamps with cool white LEDs rather than the warm white - I found them too yellow for headlamps.
I did go (way) overboard and routed all cables internally, drilling holes in pieces and using a dremel tool to make space for the LED boards and cabling.
The Biggest modification I made is storing the battery pack in the left side of the ship and modifying one of the "grill" pieces to be the power switch.
