I suggest volt ohm meter. lYou can get a good one at Sears on sale for about $10. They are very handy to have in TM tool box. For tail lights, be careful there are a lot of 12v auto bulb replacements that are ok inside, but , not DOT approved for stop/tail/signal lights.

I just went and checked and the volt meter shows 0 ohms at both wires. I may have to try the hook up light test, but I am in no position to do that right now as the TM is up on jack stands. :-(
