Small 2-1/4 inch diameter pinball bumper cap has red Art Deco style perimeter and convex plastic dome with blue numeral '4'.
Installation Tip:Change pop bumper cap lamps to LEDs even if you don't chose to use LEDs 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.
