How to tell the difference between Lewis + Bronsted

I understand the electron/proton acceptor/donor concept, but how can you tell if a molecule is a Lewis acid/base or Bronsted acid/base?
Examples would be much appreciated

A molecule can be more than one type of acid or base, it just depends on which definition you apply. For most of the problems we deal with, we are applying the bronsted definition. For example, HCl is a lewis acid and a bronsted acid.
