First try to make "working" leader lights.
With "working" I mean that I can lit the lamps (leds) in all configurations but not automatic electronically controlled.
That is because I know nearly nothing about electronics! :(
But in spite of that, I like it to see a few cars driving with this lighting on.

Place 1 in the race

Place 2

Place 3 (btw: the leds are red, but the camera think they are yellow!)
In the coming days, I hope to expand the post with more pictures how I've done it.

Using a 3D printed "lamp holder"

The leds glued in
