I've got a problem with two of my pins where certain 555 bulbs keep falling out of their sockets because of ball hits. Of course this only happens when I have a good game going, but the bulbs rolling around on the PF inside the pin screws up the current game and forces me to pause to remove the glass and re-seat them.
With my TAF this happens a lot for the two bulbs on both sides of the chair, so much that I now have them constantly removed (which sucks).
On my TZ this frequently happens for the two bulbs on top of the piano.
So, is there any good solution to this? I'm aware of that these bulbs are more exposed to ball hits than many other lamps, but after so many years of pin gaming I feel like there should be a good solution out there somewhere...
