You haven't given us enough information to figure out an answer.
It depends on whether the light bulb is part of a series or parallel circuit,
and whether there are also OTHER light bulbs in the same circuit.
-- If the light bulb is the ONLY one in the circuit, or if it's one of
several bulbs that are connected in parallel across the same battery,
and you replace it with a bulb that has higher resistance, then the
new one will be LESS BRIGHT than the original one.
-- If the light bulb is one of two or more bulbs connected in series
across the battery, and you replace it with a bulb that has higher
resistance, then the new one will be BRIGHTER than the original
one was.
