just work off the 1x1x2 block. from there you can recognize easily with practice.

In every one of the 4 cases you have one corner/edge pair connected.
Put them in the spot where they belong and hold the cube so that the 'correct' corner is either ULF or URF and the edge in the UF spot is wrong.
This edge in the UF spot now has to go either to UB (2 cases) or, depending on where the 'correct' edge is, to UL/UR (the other 2 cases).

Hope this helped.

All of them have "headlights" (2 adjacent corners with same colored stickers on the same face) and a 1x1x2 block.

Place the "headlights" facing the left side, the 1x1x2 block will either be on top, on the bottom, or on the right side (far or near). Most algs are designed to work from this orientation so recognizing it like this isn't a bad idea.

EDIT: I find it AMAZING how many replies this got in the same minute.

That's one of the great things about the forum. Many things about solving for speed are extremely personal: algorithm selection, recognition, execution. Getting many different points of view allows you to select a technique more suited to your personal solving style.
