shabbat 12

the things that might need more light to see properly:
dirty bowls, books, his & her's clothing, and lice.

or is it not just about seeing the lice, but what to do with them once they are found.

(various activities shouldn't be done by candlelight on shabbat as may be tempted to adjust the wicks, or kill the lice. for english translation of the full talmud page see here)
