Chosen Solution

I’m hoping someone can help me with a solar problem, I live off the grid and have three seperate battery systems with seperate panel arrays. Mostly I use them just for lights and I have 2 lights off each battery, two batteries are car batteries and one is a solar battery. The deep cycle battery has a monitor that I run the panels and lights through the other batteries I run the panel and lights directly to the terminals. All the lights work with up to 6w globes. My question is this, when I put a new globe in, in any of the 6 light fittings, none of the globes work. I took 4 of them back to the shop and exchanged them becasue I thought they were defective but the 4 new ones did the same thing. I don’t think it’s feasable for all of the 8 globes to be defective and this has never happened to me before and I am hoping a soalr expert out there can help me find an answer, are these globes working n a memory or something, PLEASE HELP.

Bubbles I’m leaning toward the bulbs are not 12 volt. You said they are 12 watt, which is a different thing. 12 volt LEDs are not usual. Since you have been living with your 3 independent systems for awhile, I assume you AT LEAST have a volt meter and know how to use it. If you don’t, immediately punish yourself somehow - you choose. It should be serious though. When you get one and figure how to use it, check the voltage in the sockets that you screw the bulbs into. Don’t you think that would be enlightening? If all your sockets are showing 12 volts on the DC scale, then it’s not the sockets. If some of them are not 12 volts then you have to check the battery/charge controller/array output for that system, but I still suspect that you just have 120 volt LEDs which will not work with 12
