Parallel arrangement will be used. In series combination if in case one light bulb blows off then the current will not flow through other light bulb. While in parallel combination, both the bulbs will get same voltage and resistance is less than in the series combination. 
Parallel combination draws more current as the equivalent resistance is less.
