    Can anyone tell me if there is such a thing as a polarity sensitive dc light bulb? Thanks!

    Not that I'm aware of, however it is easy to set one up with a diode in series.

    Thanks for the replies guys. When I posted the question I was working on some low voltage lighting. Most of which was feed by 12 volts AC. I should have posted a question that read something like: Is a bulb rated 12 volt 20 watt ever polarity sensitive? Anyway problem solved!
