Quoted from gweempose:I'm not sure if you are being serious or sarcastic, but I'll bite. There is no way to use incandescents. All of the inserts are illuminated by boards with surface mount LEDs.
Couldn't you rig something up as a test? I mean, get a 6V power supply and wire up a few 555 or 44 lamps and hold them under the inserts. At lest this will let you know if that lamp source looks better than the search light LEDs in there. It would be a more comparative test to the original screening if they're lit the same.
