Aftermarket lights do light it up, but the candy cane effect isn't wonderful. Do you have to pull those lights off to raise the playfield ? That would be a big drawback to me. Real mixed feelings on those. Still think I'd try additional spots on a game if it's dark in an area.
Room lighting plays into the equation too. If the room is lit decent extra lights usually not needed on most games.
Maybe somebody comes up with something new or better in the future for supplemental lighting.
