Heater Climate control led bulb size

[JDM_Rook]

Does anyone know the size for the all glass housing wedge base bulb for the manual heater controls units? In this eBay listing, if you scroll down it would be the bulb on the right in the description. Is there an Led bulb for that small base size?

I think the other 3 bulbs are T3 neowedge.
