well I have a semi truck and a light bar with 12 marker lights in the
bumper I am going to wire them 6 and 6 so when I turn on the turn
signal they flash the right way 6 will flash right and 6 will flash
left I would like to go further and make them flash in a seires
1,2,3,4,5,6, how do I do this. what relays do i need and or anything
eles I would like them to start to flash in the center at number 6 and
flash one at a time down to 1 and work there way to the out side of
the bar so it would be 1,2,3,4,5,6 6,5,4,3,2,1,and start over again.

I'd try alt.electronics group. they'd give you more answers and possibly an
off the shelf solution



The public safety/EMS market has lightbars of this nature that ARE off
the shelf. Be a pinch to adapt it to what he wants to do. Just a matter
of $$$. Google "arrowstick" or "arrowstik".. something like that..
