Hi,

I have a ceiling fixture that has two bulbs in it. One went out. I replaced it the one that went out, and it worked. I convinced hubby to change the other one as well as I am sure it will go out soon. He did, and then both didnt work. We did a whole series of changing of the lightbulbs, and it appears the lights will only turn on if the original working bulb is in its original spot, and a new one installed. If there is no bulb in the original work position but a new bulb in the non-working position, no light will turn on. If there is only a new bulb in the new position or old position, it wont work. Only one configuration seems to work.

Can someone explain? I am not sure if it makes a difference, but the original bulbs were incandescent, and the new bulbs purchased are the energy-saver halogen.

I can't make sense of it, but I am sure there is a mathematical reason for it.

Thanks for helping.
