How many diyas should one light on Choti Diwali?

According to Hindu traditions, 14 diyas are lit during the Pradosh period on Choti Diwali, also known as Narak Chaturdashi, but at least five diyas must be lit. A 'Yamadeep' (diya for God of death) facing south is either placed outside the main entrance or near the drain. People pray to Yama for protection from the dangers of premature death.
