Quoted from pcprogrammer:
How much do these leg light ups cost?
They are $85 per kit (2 legs) with Free shipping in the lower 48, they are Plug-n-Play for Stern games with the Molex 12/5v plug under the shooter rod in the cabinet. Each kit comes with 4 of my exclusive Super Tough leg bolt washers as a Free gift. As you can see from Ipierrics picture they do light up some from my mod which looks cool.
