I am restoring a couple of radios that use dial lamp #47. Is there a safe substitute or another lamp in place of this lamp that would make the dial brighter?
Thank you

i think u would have to worry about melting a dial scale or putting extra strain on the circuit for that. u would need the same voltage bulb but higher current which might burn hotter and strain the filament tap

Thank you, I guess I was trying to avoid the obvious.

Hi Vinny

Not much you can do. A #47 bulb is used in AC/DC radios with tubes having 150 ma series string filaments. If you use a higher voltage bulb there isn't enough available to light the bulb. A higher current bulb, such as #44, is also dimmer as the circuit can't supply enough current either.

If a #47 bulb is in a radio with a power transformer a #44 bulb will be brighter.

Thank you norm, at the risk of sounding obsessive and like a shoemaker, is it possible to surround the light (as close as possible)with say tin foil or any other reflective material.

Vinny,
For what its worth, had a Philco 42-350 with a special metal reflector of sorts on each bulb to the left and right of the dial. It was tubular, fitting over the bulb and socket. The front half was shaved away so the light left the bulb horizontal to its axis, which didn't light up the dial/pointer very well. Rolled up a piece of white shiny construction paper to fit down over the bulb/socket, taped it, and now the light escapes from the top of the bulb toward the dial glass/pointer. Lights up the dial and pointer nicely, with no obscene shadows etc.
