On our 1998 International 4700 dash, the switches on either side of the cluster are not back lit but simply lit by a single bulb located at the top of the switch banks. The bulb is dim and does not do a very good job. Has anyone replaced this bulb with an LED? If so, would you know the size?

 

I'm guessing a 194, pretty common in dash panels and widely available as an LED. Figured I'd get some more eyeballs on your thread anyway. Had any luck in the meantime?
