I don't know anything about Rabbi Shmuel Shapira of Kochav Ya'ir, but I like his response to a question in YNet's "Ask-the-Rabbi" column: Q. What is the significance of a Shabbat candle that went out three times? - Revital, Petach-Tikva A. Shalom Revital. Generally, the explanation is that the candle is deficient, or that there is a wind in the place where you light. Therefore, you should change either the candle or the place where you light.
