ROTO POOL (Gottlieb 1958) Pop bumper cap set (4)
1958 Gottlieb® ROTO POOL pinball machine 4 piece pop bumper cap set.
Change pop bumper cap lamps to LEDs even if you don't chose to use LEDs elsewhere in your machine. This prevents 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.
