Eiko #555 bulbs are used for lamp matrix and backbox applications in most WPC pinball machines. For pop bumpers, we recommend #259 rough service bulbs which will last longer in a pop bumper.
We also stock #159 bulbs. These are the same size and voltage as a #555, but use considerably less power. The #159 is a good option for backbox bulbs in a heavily-loaded machine, as the lower load will prevent connector burn
