I have Electrohome 850 receiver w/turntable. Needs indicator bulbs for stereo,FM and AM bulb. It had incandescent bulbs looks like 5mm wired. Measured voltage going to bulbs . It's around 11V AC (not DC).Purchase some 12V wired incandescent bulbs online and all see very dim. I'd like to keep it original so I'm hoping to keep incandescent. Is there something I should be looking for when purchasing these bulbs as far as current or wattage? I'd rather not deal with LED's. I've heard you have to use a resistor in order for them to work properly. Clear or white would be great.
