It is a 12 volt axial lamp. There is no brand listed on the site, and the only numbers they have are their own stock numbers, so searching for those numbers only takes me back to that site.
Here is a link to the part:

The current rating could be lower, and the voltage rating could be slightly higher, and it would work. This would also work:

(I am wanting it for lighting the meters of an old Carver power amp. So I will probably buy two, and replace both lamps even though only one seems to be burned out [they wire in series, so there is no light with only one good lamp], so the lighting will be the same for both meters.)
I am getting the impression I am going to just have to pay much more for shipping than for the part. The only local electronics supply store (other than Radio Shack, which also does not have it) I know of has none listed in their catalog, which does not surprise me, as it is not much better than Radio Shack used to be, which, as has already been noted by someone else, is not what it used to be at all for this sort of thing.
The shipping charges for this part are excessive, but if I cannot find anything local, I will either have unlighted equipment or pay too much for it. But I would like to know of a good local electronics supply store for the future as well, as this sort of thing comes up from time to time, so it isn't just this one purchase that matters. It would not be worth my time or yours if this was going to be the only time ever that I would want to know where such a store was located. And, if there were a good online listing for this sort of thing, it would help other people who are in a like situation, which makes it all even more worth everyone's time, if such a thing exists.
