Pardon my dyslexia, I meant to say if you have a positive ground Healey, a typical LED lamp bulb replacement will likely not work, negative ground Healeys will be fine.  An incandescent bulb indeed does not care about polarity.  Sorry for my absentmindedness!

While it may work fine, and it doesn’t matter if the battery charging device is a generator or alternator, LED bulbs do care about polarity, so if you have a negative ground Healey, check with the bulb manufacturer to see if the bulb you need/want is available for negative ground polarity.

Yes it will work just fine--bulbs do not care about polarity or source of power.

They sell a LED bulb as a replacement. A lot more expensive but will it work on my alternator converted car ? I assume a lot brighter.
