From the looks of the setup (a Moiré system) you'd want reasonably uniform

Originally discussing RK05 head position sensor
bulb. I have replaced it. The
offical part to replace it isn't available. You can open it up and put in
a new bulb. I wasn't able to quickly find what bulb I used a number of
years ago but if someone really needs to know I can dig further. One of the
small ones with wires. It doesn't use bulb with base. LED didn't work. I
think sensor is IR.
I have also replaced it many years ago. I bought a hand full of 5V micro miniature light
bulbs with wires. I think I bought them at Bürklin back then. Anyways, they were a 1:1
match and the replacement works like a charm. I guess that the filament orientation in the
buld is important and that it should be parallel to the graticule.
