When you speak of terms of "needed", a lot of the mods done are certainly not needed. As far as the elderly comment goes - the elderly are far more inclined to be purists. I may not be elderly (52) but I actually prefer incandescent lamps in most of my games. I think it is the young that are more inclined to add colored LEDs in all forms, and as they increase in the hobby in numbers they are more likely to be the buyers of colored posts, LED strip lights, lighted speakers and so forth. I've posted about that before...my son has LED remote strip lights on his walls, his computer keyboard has rainbow LEDs throughout, and bubbly liquid filled LED computer speakers. Thank God he isn't interested in buying a pinball because I know exactly what would happen.
