Quoted from german-pinball:... and if anybody would like to build a "universal" board for Bulbs #89 and LEDs, a second resistor and a jumper could be added ...

I'm not sure if I'm reading it right, but should the lamps be connected to the middle common pin for the jumper, rather than one of the outer pins?
Quoted from german-pinball:For the jumper, there is a 3-pin Header.
If set in the LED-configuration we have R1 + R2 in parallel and a total resistor value of 5 Ohms, as needed for the LED configuration.
In the bulb #89 configuration, the resistor R2 has no effect and we "only" have R1 active with 10 Ohms, as needed for the bulb #89 configuration. For the bulb-configuration, you could leave the jumper complete out, but if it is set, you cannot loose the jumper, it is only a "parking-position" for the jumper.
The input and output connections of nerdygrrl´s sweet board are drawn in the schemtic with )-- and --( ...
Hope, that helps ...
Oh, I see--I didn't even look at the resistor values
