Heater backlight bulbs

[Cornishman]

I am looking for a source for bulbs that backlight the heater display, they are tiny and push in. Ideally a UK European supplier.
Thank you

My notes say that a #2712, 12V 1.2W bulb fits a '73 and newer. The same bulb is used in lots of cars and was available at a local car parts store.
