Brand new... Indicator lamp for IFR test equipment- These are used on the IFR 1200Y3, and the IFR NAV 750/750A/750B. There is probably other IFR units that use these lamps. If you have just been putting off ordering that ridiculously expensive lamp from IFR, or just can't seem to find a good source for these, you are in luck.... buy a couple of these now, and check off of your, "I'm going to do that one of these days" list.
