The main light switch when you walk in the MH turns on 10 bulbs in 5 dual ceiling lights. if I go and manually turn off several (half) the lights, the LED will light as designed. If I plug in to shore power, I can have all the lights on and the LED will still light. Haven't taken a voltmeter reading yet, but must be real low when off shore power (strange as my interstate batteries are only a year old). So I'm thinking if I change all the bulbs to LED, I should be able to run most the fixtures at he same time. On my next LED purchase, I need to buy lower voltage bulbs. Thanks again.
As far as I know, you cannot buy "Lower voltage" LED bulbs. LEDs operate in a range of voltage. Usually not lower than around 8-9 volts and, not higher than around 14 or 15 volts. But, all of them require a resistor anyways to drop them down to around 2.5-3 volts anyways.

Try to supply an LED that is not resistor equipped with a full 12VDC and watch what happens, POOF!
