Hey guys,
I have this neat old Zenith Circle of Sound clock radio from the mid-70s. It still works well; the radio is very strong and it sounds GREAT for a clock radio.

The mechanical clock part even works. However, one of the backlights for the radio dial burnt out recently. The lamp does seem to be replaceable, but I have no idea what kind it is. It's basically a tiny little incandescent bulb with a rubber holder/socket. I haven't tried removing the lamp yet; not sure if it just slides out or if wires will need to be spliced. I can always solder in a new lamp if necessary.
Any ideas on what kind of lamps these are? Here's some pics if they help:

Any ideas? Please let me know what kind these are so I can find a replacement lamp to get the dial fully lit again!
