נר ה' נשמת אדם                                      
There is no mention in all of Shas

, about Ner Neshamah (Yahrzeit Licht)

The Mishna in Ms.Brachos (53a) that says not to use a Ner Shel

Meisim for Havdalah,refers to a candle used for the Levaya etc.
and not a Yahrzeit candle, which probably may be used for Havdalah.

The Gemoro in Kesubos (103a) Rebbie left a Tzavo’oh  with his

sons to have a candle burning  at the table,  refers  to
Shabbos candles.

The first mention of Ner Neshama is probably the Kol Bo in

Hilchos Yom Kipurim. The Kol Bo writes to light a Ner
for deceased parents, on Erev Yom Kippur, so they will have
a Kapparah.

It is very likely, the parents have a Kapparah,because
of  ברא מזכה אבא  , The Mitzvohs a child does benefits

the deceased parents.
The Tur writes (630) There is a special Inyan to have
lots of candles in Shul on Yom Kippur.
In the olden days, the largest and one of the few

expenses  a Shul had, was Ner Lamo’or. Bees wax

was a very expensive commodity .

It is very possible, the Chachamim tried to entice  people

to donate Ner Lamo’or, so they attached the special
Segulah of Kappara for the Meisim, a Siman Tov for the
living and the Ner Hashem Nishmas Adam for a Yahrzeit.

The Ksav Sofer (Shu”t O.Ch 68) is Matir to light a

Yahrzeit candle (preferably in Shul) on Yom Tov

because people consider lighting Yahrzeit  Licht more

of a Mitzvah than any other Mitzvah  in the Torah.

So not to be sad on Yom Tov (שמחת יו"ט ) he may light it

even though it is לא לצורך
