Quoted from parsonsaj:
I have something that I hope is more of a question than a problem. I have a Pro, and am wondering what is supposed to cause the right ramp flasher to activate? (This is the big yellow flasher at the top of the right ramp). I can test it in the diags and it works fine, but I don't think I've ever seen it come on during normal gameplay. I thought this was odd since this is the recommended flasher to control Pinstadium lights for this game (I used another flasher for mine, but was thinking that if I HAD used the recommended one I wouldn't have got much in the way of results!)
I thought the same thing about my pro after playing a LE on location. I had noticed that flasher going off quite often on the LE, and after thinking about it I couldn't really remember if it was even there on the pro. Went home and confirmed that there was actually a light there, although the LE light cover is blueish instead of yellow, and possibly a little taller. I fired up a few games, and confirmed that it does work the same on my pro, however the plastic cyborg cut out on the pro obstructs the light much more than the cyborg toy figurine on the LE. Of course that doesn't mean yours isn't working properly, just thought I'd point out my findings.
