Need a little help with a 12v on off problem

Hel all,

Need a little help here....

I have a light that comes out of the back of a machine at work that runs at 12v.

The problem is that when the machine is on the light is off and when the machine is off the light is on. I need to change this somehow.

is an inverter the kind of thing i need? I am willing to pay for something that will work if no one knows of an off the shelf product as i will be needing a few of these

Hope you can help!

That sounds a bit dodgy.

How is the light controlled from within the machine?

Is it supposed to do that?

It sounds like a relay has been wired incorrectly.

Apparently thats the way its supposed to work we buy them from china.

is there a solution to the problem as i said i really need to sort this via something inline and am willing to pay for help!

Ask the Chinese, it's their machine after all. Without knowing the details it is really hard to say what is going on inside the machine, or what you might do to change the behavior.

You first need to show us the circuit digram of the machine, it's probably quite trivial to change - but we need to know exactly what the circuit is.
