I finally got around to fixing my scoop post lamps. The original bulbs had melted the sockets slightly and new bulbs would no longer stay in the sockets firmly. I would end up having to go fishing for fallen bulbs every few games or so. I traced the melted sockets as the source of frying a transistor on the lamp matrix too. I fixed that previously but I've had two of these sockets disconnected since.
So after about a year I've finally fixed these socketsSo after about a year I've finally fixed these sockets

The original wire connectors were too lose on these replacement sockets so I had to solder the wires in. I may regret that later on but at least I know they won't come unpluggedThe original wire connectors were too lose on these replacement sockets so I had to solder the wires in.

I checked the wiring about six times before soldering. Removing the solder on here will be a nightmareI checked the wiring about six times before soldering. Removing the solder on here will be a nightmare
I also changed out my cheap PBL rubber caps with ones much more like the original. I'm using the thick rubber caps over my LEDs. I also changed out my cheap PBL rubber caps with ones much more like the original. I'm using the thick rubber caps over my LEDs.

I replaced 4 of the 6 sockets. I wasn't having trouble with the remaining original sockets. The job was simple enough so I'll likely order more sockets next time I order parts from PBLI replaced 4 of the 6 sockets. I wasn't having trouble with the remaining original sockets.

Played a few games and the bulbs are holding strong in their new sockets. Anyways, just an FYI post in case anyone else is having this problem.
