The ones from Radio Shack (276-0027) are green 4 pin (not the multi-color type) there is one corner that looks flat (like some bridge rectifiers) and is the cathode side. The cathode is the side with two redundant pins that connect to the center light emitting element. The anode is the side that is like a narrow bar running across the top to connect to the other anode pin.
It's really just a standard 2 pin LED except it's flat and the 2 additional pins are just to hold it nice a tight on your board.
If you look at it close, you'll see that 2 pins go to anode, and the other two pins go cathode.
Hope this helps.
