Hello, can anyone tell me the bulb size that goes behind the maplight on the dashboard bezel, please?

May be a PC 161 but I can't find any.

Thank you! 

 

The 1977 280z has the same map lamp bulb as my (UK) 1977 260z. I am not sure what the bulb-type model reference is, but looking at my UK R-Drive fiche the Nissan part number is 26261-89903 (from 08/73 on), which still appears to be readily available, new.

Here is the updated part number: 26261-89965. It looks to be a standard type 194 bulb. I seem to remember using an LED version in my map light many years ago.
