# One isn’t allowed to read by a candle (wick in oil) on Shabbat because there is Gezerah that one will come to tilt the wick. <Ref> Mishna Shabbat 11a says that it’s forbidden to read by the light of a candle because one will come to tilt the wick. Rashi explains that if one tilts to wick (which is flickering) towards the oil so that it lights well, one will be violating Mavir (lighting a flame on Shabbat, which includes adding fuel to a flame). S”A 275:1 quotes this as halacha. </ref>
