Got a nice RfM this weekend and looking to restore it where I can.
One thing I noticed is that not all the lightbulbs on the playfield have a red silicone lamp cover. So I ordered a bunch of them (https://www.marcospecialties.com/pinball-parts/03-8063-4), but can't figure out which lights originally had one of these covers. (the manual doesn't mention them, and it's hard to see in online photos and videos).
Anyone here can help me identifying where they should and shouldn't go?
