I fail to see the usefulness of combing a butane lighter and a flashlight.
YMMV

Having said that, I do have a couple of lighters that each include a TORCH ( meaning a jet flame), as well as the usual slow flame.

IIRC, they have two refillable butane tanks.
They are essentialy two lighters in one.
