I forgot where i saw it, I’d imagine it would probably be found in the sefer “minhag Yisroel Torah”, that its a segulah to relight the havdalah candle after you put it out to prevent a fire in the house.

Where is this tosefta? The only thing I found is the gemarah in Pesachim 42a “3 things … and take 1/500th of a persons sight:pas kiver (buried bread??) fresh bear and fresh vegetables (see rashi)…3 things…and enlighten the eyes: clean bread, fatty meat and old wine”.
The psiah gassah thing is from Berachos 43b and Shabbos 113b that psiah gassah takes away 1/500th of a persons sight and the cure is kiddush on friday night (some say from drinking the wine and others from looking at the neiros durring kiddush)
