Even without the light board that Tsskinne refers to, replacing with a socket (in bulk from Pinball Life is $1.05) and a Comet LED (bulk is 0.59) and the math definitely works out for these yoppsicles. Add a resistor for $.02 and you are good with your original Bally lamp board. Or go with the light board as Tommy mentions or get the Seigecraft boards for less soldering.

I'm going to definitely consider these in the future.

Any plans on how to implement something for GI lighting or will we still have to use the ol' socket/bulb combo?

I was thinking for PF swaps where I would replace all the sockets anyway. I replaced the sockets on my FG and Viking swaps. Were these available at the time, I would have considered these for inserts and star rollovers. At $1 each, it would have saved me $.64 on the bulb/socket. Over the 2 games, it could have been $120 or more. I'm doing a Centaur swap and a Joker Poker swap within the next year, so getting a couple hundred of these might be in my future.

For games that I don't do swaps in, the yeah, I would replace the socket/bulb on a "per" basis.

I do and I didn't save them. Only seems wasteful if they all worked 100% of the time. I mean some did, but some didn't and the time saved to replace them all was worth it. I think it's a pretty common practice when doing swaps. Marking the bad sockets, desoldering them all, sorting between the good ones vs the bad ones, it would take a ton of time. Plus, it's a new pf, it should get new stuff

This is what I use on my older games. Yes!
