Replacement backlight bulbs for wildcard box

I have a wildcard switchbox for the Spectra (the one with several on-off and momentary switches.) The backlight bulb inside one switch is burned out. Does anyone know the part number of this bulb, or the spec's of an equivilant bulb? IT actually looks like I might need to replace the whole bulb housing...

I had one of these units where I had to replace the backlight as well. When I cracked it open, it was a series of green LEDs. I don't recall exactly what the voltage was though. As I recall, I fried one or two because there is voltage applied to them when the ignition sense is active and additional voltage is applied when the switch is on, increasing the brightness to indicate the switch position. You should be able to crack open the unit and put a meter across the LED. Just make sure that you take the measurements when the switch is in both positions. It may also be to your benefit to replace all of the LEDs at the same time... this way you're sure to get the same color backlight across the enture unit.
