METEOR (Stern) Pop bumper cap set
1979 Stern METEOR pinball machine pop bumper cap set has small "1" and 3" stamped caps and large cap with star.
Change pop bumper cap lamps to LEDs even if you don't chose to use LEDs elsewhere in your machine. This will prevent the pop bumper caps from incandescent lamp burn as the lamps age and overheat. A warm white LED (see related items below) is a perfect substitute for any pop bumper incandescent lamp.
