I believe your only option may be new. There is one single color LED replacement I’m aware of by Boston Pinball, and a multicolored one from PinballSP that is very close to production. I would suggest PinballSP, but if you don’t want color or want to spend less money, go with the Boston Pinball one.
New! Dark mode!
