Opposite of Bang Tight, however instead of talking about a women's beauty it is used to describe a product and/or service which is of poor quality or cheap.

It can also be used when some has let you down or not fulfilled their side of the bargain.
Man the trainers that guy's wearing are bang light.

Frank was well Bang Light, he could have at least brought the beers that I asked for along.
