need help finding out what size bulbs fit the itr foglight button



Picture for reference

 

I've got a USDM cruise control switch I just took a look at, both bulbs are formed with a white plastic like the ones in your picture. I can tell from your picture one of the bulbs has a "S" and "C" marked on it. One of the cruise switch bulbs has the same letters on it.

Can't tell what your other bulb has marked on it but my other bulb on the cruise switch has the letters "S" and "H" marked on it.
