I need to replace the light bulb for the radio in my '65 Buick Wildcat.

The radio is a Delco Sonomatic 7289734 (U7N137), AM only, no wonderbar, and is part of a fairly common family of radios installed in mid-'60s GM products.

The bulb appears to be marked with the number 294. This number isn't an off-the-shelf part at NAPA and a cursory Google search turns up some LED bulbs but nothing incandescent.

Doing a search for "Delco radio bulb" brought me to This Interlight Page which gives a part number of 7290302, but that doesn't seem to cross-reference either.

The closest I've come based on other bulbs used in the vehicle (according to NAPA) is #1445.

Does anyone have any experience with this radio and/or bulb that can suggest a better match? I'm willing to take a less-exact match to have something I can pick up at one of my local auto parts stores.

W294

Update

Since I was chasing another issue with the radio in another forum, I also asked this question there, and was given bulb #293 as a candidate.

I appears you need a G3.5 or G3 1/2 bulb with a bayonet base. It is also referred to as a mini indicator bulb. Looking on amazon, there are still some companies that make them.

If you want to go to the parts store (or radio shack) and look, your specs are:
~3/8" diameter base
~15/16" length
bayonet base

10 pack on amazon: https://www.amazon.com/Eiko-Indicator-0-135-Miniature-Bayonet/dp/B003R3LAQA/ref=sr_1_7?ie=UTF8&qid=1476980153&sr=8-7&keywords=G3.5+bulb+bayonet

Some that look close:
SYLVANIA 53
SYLVANIA 57
GE Lighting 53
GE Lighting 25550

You should be able to find a '53' or '57' bulb at most auto parts stores.
