What lights on the playfield specifically? I haven't been under the hood of mine for awhile, but if memory serves most of the playfield GI uses a wedge base (555), like these:
I know for sure the yard marker lights use these, just make sure you get the wedge base, as well as the 555 twist in sockets for each one, in case you don't have them. Like these:
I would check and make a list before you order though, because I know there are a number of flashers under there as well that require a larger socket. You'll want the 906 base for those.
Thats all I can think of off the top of my head, but once again, I'd make a list before making another order because I know there are some bayonet base lamps mixed in there as well, like the lights for the skill shot off the plunge.
Good luck, and congrats on the pickup. I love this game.
