Welcome Dave, glad to have you!
Still wondering how you pulled off the sequenced flashing feature on the LEDs
I've used some electronic platines, ICs, resistors and transistors to generate this "running light" effect. It is done with a lot of soldering, soldering and soldering.
You also can buy such electronic circuits ready as kit. Here in Germany we have an online shop named "Conrad Electronics", who has a "6channel LED running light kit" Ouh, I just see, they have an international shop: An Example is Order number: 190128 on http://www.conrad.com
. But also here: soldering!
OK, it is not perfect, but I hope this is the answer you wanted to hear??
