which wire?

I am sure this is a simple question so I accept that fact it and I may sound a little dumb asking but here is my question:

I bought a new Perko stern light. When I opened it up I found two black wires. I saw nothing to indicate which is pos or neg. The wires in the boat and on the old stern light are what I expected in the new light red and black. Hearing all the horror stories about faulty wiring damage I do not want to hook it up with out checking, is there some clue indicator that I am missing on the black wires or does it really not matter which is pos or neg when hooking up a stern light?
