Quoted from Toasterdog:I was under the impression it went to any GI bulb and basically just stayed lit up. As the ball rolls through it, the ball makes contact with the lower portion of the reels and spins them.
Maybe I had the generic model though, lol
This is my recollection as well in regards to hooking up to a GI bulb. I thought as well that the reels would move automatically, but they don't, they move when the ball passes through.
Don't tighten too much and you shouldn't have problems with ball hangups.
