Quoted from mwong168:I made my own dual beacon interactive topper similar to Dave's from pinballtoppers.com. They are set to go off when you start multi-ball, jackpot, left plunger lane for flying rocks and the top roll over switch when you hit the right ramp and it feeds back to the mini left flipper.
I documented exactly what I did here for those who want to build their own.

Hey - thanks for posting that! I learned some things (gave me some ideas) off your very detailed instructions.
... and Road Show IS a great pin!
