panel. So, might anyone be able to tell me what kind of
bulb I need to get
to replace the bad ones, or how I might be able to use LEDs instead, which I
would prefer, as I don't want to be replacing burnt out bulbs all the time.
Rat Shack isn't the place I would look, cheap LEDs are common at most
hamfest though. How is this for an idea, take an old burnt out bulb and
carefully remove the glass and innerds, then solder the LED and its current
limiting resistor into the base of the old bulb. The key is the current
limit resistor, which you calculate from the voltage applied to the bulbs.
BTW I am sure people sell bulbs with LEDs like this as replacements.
