Why must I hate you? I just threw my kit out the window becuase I knew I would never be able to make it anywhere near as good as you did that one.
Very nice, very nice indeed.

Should have put it on ebay, instead
Waiting on the next coat of paint to dry.
Here's the electrical diagram I've been promising -
The resistor values are what I used, but aren't strictly accurate - the LEDs are each 2.1V, 20mAmp. Using a 9V battery, the Resistor on the White circuit ought to be 172 Ohms. And on the Blue circuit, 115-Ohms.
100s I had handy, 100s I used.
The Diode functions as a one-way gate. With it in place, turning on the blue (engine) LEDs also energizes the other circuit. Make sure you don't put it in backwards. Digging for the Diode specs, don't have'em handy, but it's basically whatever range will handle a 9V battery.
You can use whatever battery source you want, and adjust the equation accordingly for the LEDs.
(Battery Voltage - Light Voltage) divided by Light Amps (in whole Amps, and combined for a couple LEDs), = the desired Ohm rating of the Resistor you need. For a simple LED-lighting circuit, 'close' is good enough. LEDs have a current draw measured in milliAmps. 20 mAmp is typical. To plug that into the equation, move the decimal 3 places to the left, .02
It's easy
