16. If, when the candles were lit, they had the potential to burn for the requisite amount of time, one does not need to relight them if they went out sooner. This is true even if they went out before Kabbalas Shabbos on Erev Shabbos, which is still daytime (שו"ע סי' תרע"ג ס"ג ). One who wants to be machmir and relight them should not make a brachah since he already made the brachah when he fulfilled Chazal’s enactment to light before shekiyah on Erev Shabbos (רמ"א ).
17. Some say it is proper to be machmir and relight them, especially if they went out on Erev Shabbos before Kabbalas Shabbos since on Erev Shabbos, they are not lit at the time of the chiyuv. Still, one should not make a brachah since he made a brachah when it was permissible to do so (ט"ז סק"ט ).
18. If a person’s menorah went out after he took in Shabbos, he may ask someone who has not yet accepted Shabbos to relight them for him (מ”ב שם סקכ"ז ).
