Get yourself a cheapo test light or multimeter. Very handy to have when working with car electrics. The likes of Maplins can supply or if you are feeling adventurous amke you own from a 12 volt bulb and a couple of lengths of wire.

Yep, as above, you need a meter as that's the easiest way to identify polarity. A bulb alone won't identify polarity. It would with a diode in series though.

Without seeing the wires in context I'm only guessing, but if they go to a headlight bulb then one will be ground and the other two the 12 volt feeds (one for each filament, dipped and full).
