6v pilot lamp

[KA2PTE]

Trying to locate replacement bulbs for an old Wards transistor radio, they are 6.3V
but only 20mA rated. Higher rated current lamps are out there, but in this design
they dim the bulb when you tune a station, so looks like they must be that rating.
 
I thought an 1175 lamp would do but the current is wrong. It has to be a T5 screw type
socket. Could not locate a bulb number for it...any ideas?

Hit me up, hundreds of vintage lamps here.

I'm good on the Zed.
