Does anyone have a part number and source for the small light bulbs that are used in the console indicators for Choke, Fasten Seat Belt, and Rear Window Defrost switch. Mine just say 1.5 watts, 12 volts. Car is a '72. I've searched without any luck so far. Thanks.

Do you have the old bulbs in hand? If so, I could probably tell you the type.

 

Could they be 194s?

Here is a picture of two of the lights.  The base is 0.268" in diameter.

I found a part number on the microfiche but no images of it.  It's number 23.

Thanks for posting a picture. It's a BA7 bulb. Here's a source: https://www.superbrightleds.com/moreinfo/ba9s-ba7s/ba7s-led-bulb-1-led/10/#/attributes/16.

Thanks. It is also available as a regular bulb Eiko 16037 - 3898. I ordered the LEDs. I'll update when I get them.
