I have a light issue on the boat. My port light is inoperable. I replaced the bulb and it didn't work so got the multi-meter out and checked the fixture. It has 12volts going to the posts that contact the bulb. So I thought maybe it was just a factory defective bulb. I took the bulb out of the starboard side that was working fine and put it in the port fixture. Nothing. I placed the new bulb in the starboard side and it works fine. One other curiosity is once the bulb is in place there is no longer current to the posts. I swapped them back again to check if the fixture had shorted and blown the bulb. Both bulbs work fine in the starboard fixture. Baffling to my limited brain capacity!

I realize of course the simple fix is just buy new fixtures and I plan to do so ASAP but I am just curious as to why/how this could be happening. Anybody have any ideas?
