I am hoping that someone(s) can help me with doing some modifications to a circuit I found on here that indicates the winner of a pinewood derby car race. Here is the circuit I found;


What I would like to do is to add an additional SSR to each lane. Then, re-work/add to the circuit(or just come up with a new one) that would light up a light for first and second place, and leave the 3rd place dark.

Of course, I suppose if it was not too much to do, maybe add an additional relay to each lane, and have a 1st, 2nd, and 3rd light.

Is this too complicated? I am going to try to wrap my mind around it, but thought you all could help me along. I do not work with circuits all the time, just a little here and there, so sometimes it takes me a while to lock onto something.

Thanks for the help in advance!
