If your equipment calls for a #47 or T47 bulb, this is the direct equivalent.\u003c\/p\u003e\n\u003ch3\u003eWill these fit my pinball machine?\u003c\/h3\u003e\n\u003cp\u003eYes — the #47 is one of the two canonical pinball bulbs, used for general illumination on nearly every machine, in both the playfield and the backbox. They install with a push-and-twist into any BA9s miniature bayonet socket.\u003c\/p\u003e\n\u003ch3\u003eWill these fit my Fender amp?\u003c\/h3\u003e\n\u003cp\u003eIf your Fender tube amp uses a #47 pilot light, yes — that covers most Hot Rod, Reissue, and vintage-reissue models (Hot Rod Deluxe, Twin Reverb, Deluxe Reverb, Princeton Reverb, Blues Deluxe, and more). They do not fit the Blues Junior or Pro Junior, which use non-replaceable LED pilot lights.\u003c\/p\u003e\n\u003ch3\u003eAre these the brass-base or nickel-base bulbs?\u003c\/h3\u003e\n\u003cp\u003eThese have the brass-colored bayonet base shown in the product photo. The base is what locks into the socket — brass and nickel bases are interchangeable in any BA9s socket.\u003c\/p\u003e\n\u003ch3\u003eHow many do I need?\u003c\/h3\u003e\n\u003cp\u003eA typical pinball playfield uses a mix of #47 and #44 bulbs; a 10-pack covers a refresh with spares.
