Don't think they can work with the u360 because of the base of the joystick.  If someone can do it I be inline to buy some.
I was hoping they fit in the u360s so I could pair them up with the GGG merchandise.  Seems like a match made in heaven.  Ohhhh RAAANNNNDDDYYYYYYYyyyy...

   Randy and GGG don't make either the balltops OR the U360.  What's Randy supposed to do?

And no, there's no way to mate these to a U360.  The plug for the balltop lighting is in precicely the place where the magnet needs to be on the U360.
I was insinuating that maybe he could come up with a clever add-on handle for the u360s.  They seem to be pretty popular now that various front ends auto-map the controls.  Can't shame a guy for wanting lightup handles AND automapped controls can ya 

I suppose given current options, I would try to find a white balltop for the u360 and see what happens in the land of lightup tops.  Thanks for the info!
