Gentlemen, I installed six annunciator lights from two old autopilot systems in my panel. Now that I am testing the wiring, I find that 10 of the 12 interior bulbs are burned out. The lamps are tiny--0.155 diameter at the base, and 0.36 tall. They have a number: OL-6839 stamped on the base. ACS lists some small bulbs that are "1/8 inch in diameter" but the part numbers are not similar at all. Is this the same bulb? Would anyone have another source for these?

Thanks,

Bob Pastusek
