PS Edit: after re-reading your talking about the light bulb in the steering column switch?, there are different types depending on the unit, from below, Turn Switch 1873 3cp 28v 5.6w 249 / MCC / BA9S (remove the green cover by unscrewing and push down the light bulb with a twist to remove/insert) older types have a special smaller bulb within the stalk end, none of those will be listed below.

Original message:
Might ask which model, for the A1 will be different than the A2 cluster turn signal. There was a listing many years ago on 24V bulbs, and NAPA sells them from memory.
Then there's this old post Ken provided in 2014:

"There's ALWAYS a list ! Here's one I put together a few years ago. :D

Hey thanks for that information.

It’s for a 151a2. On the column with the green cap ya gotta remove. It’s not in the stalk.
I also corrected the post to reflect that it’s for the A2.
