Quoted from pinballphile:Finally, the reason I'm replacing the translite in the first place, is that part of the "Tallking Tina" face on the old translight was rubbed away by the long clear plastic post screwed into the bulb board behind the translite. I got rid of that post to avoid further damage, but was wondering what purpose it serves, since it appears in my STTNG as well.
I believe the post you are referring to works like a door stop for the hinged panel that houses the lamps. Without it, the door could hit the side edge of the backbox and break lamps or cause other damage. Normally, it should not come in contact with the translite like that, though.
