Quoted from Gott72:

Do LEDs ghost in the 70's Gottlieb EMs?

Is it necessary to buy anti-ghosting LEDs for these machines?

No and no.

Ghosting is primarily a cause of certain flaws in solid state games. None of that circuitry is present in EMs.

Quoted from Gott72:

I'm going to switch over a machine and would hate to order loads of useless bulbs that go into the trash.

If you don't like them, you can always resell them. I've sold a bunch of LEDs I wasn't going to use, and I've seen others do the same. No need to trash them if you don't end up wanting to use them.

Quoted from stashyboy:

Agreed. Every Gottlieb EM I have ever worked on would ghost in the feature lamps. GI circuit generally not. I use non-ghosting in the feature lamps under the playfield. Avoid LEDs on top for ascetics.

The Gottlieb EMs I've owned or worked on didn't have ghosting issues.

Since there's no electronic circuitry, what could even be a possible cause?
