Now I unde5stand what you mean by a ''signal strength indicator''

 I guess I just call it a tuning light,   On my Rogers 10-12 There are two of them, and on my Rogers 6R932 there is one in the very center if the cabinet.
   I also have one in my DeForest Crosley 'Buckingham, and some of the tombstone models have them also.
 
 It took me quite a while to find the right bulb,but once I did  I ordered 20 of them, because I am always running into Rogers radios.
  The biggest thing about the bulbs,   [I found ] was the amps had to be just right
  The bulbs that do the job are   #1448.
