1) the "numbers" are for the "match feature"... i.e. if your last 2 digits match them, you won a free game...

2) the bulb could be burned out, or there could be something not triggering correctly, likely a switch on the 10'000's reel...

Ding Ding! We have a winner!
I think the match numbers still light after a game, no matter how the extra ball / relplay / novelty jones plugs are set.
Yes, the 100,000 should light when you roll over the score reels back to zero. That's a pretty good game of Gulfstream at that point! Feels great to do it.

Williams of that era have a jones plug to disable match which will turn off the lights

do you have the game set for-
Novelty, extra ball, or credit ?

Take the bulb out and check it w/9volt battery (one term to base other to tip) or meter.
Could be a bad socket too.
Manually run the score up to check the operation after installing before putting B/G in saves aggravation.

the match was a gift from the pinball gods... if you'd fed the machine your last dime and there were no credits left on the reel, hearing that knocker go off after watching your last ball drain was a real rush...

fix the knocker... it is the best sound in pinball...

as far as the score reel goes... i'm a definite rookie here, but it seems to me that the great majority of issues with score reels are caused by good old grunge, and spending a few minutes taking it apart and cleaning it will make many problems go away... replacing any tired springs seems to be a good preventative maintenance item while you have it apart, they've been "used" a bazillion times and new ones are cheap... again, i'm a rookie, but if i've got something taken apart, i think it's wise to replace any inexpensive wear parts...

the small percentage that cleaning doesn't fix seems to always be the 9 and 0 switches...

Gotta have the knocker - it's a cool sound!
I'm a rookie too & just replaced my knocker on my GS and IT WORKS!!

Love Pinside for stuff like this! The match feature! Who knew?

Truth!
