docking lights activated when backing and signaling turn,?

I didn't have the idea to flood the entire aft area. In mounting them in the wheel skirt to raw the back of the tire. There's a running light/turn indicator light in front of the tire. I thought it'd be useful for late night turns and to give a little more warning to someone sneaking into the lane at the last second like they do. But now that I think about it, I think I'll just use em with back up lights on.
