Q. Can one search for chametz when in jail, if you can’t use a candle or a flashlight?

A. Horav Shlomo Miller’s Shlit”a opinion is that in those in exceptional occasions when no candle or flashlight is available or permitted, such as one imprisoned or hospitalized, bedikas chometz should be done using the existing light available.
