Just so you know I am very good with wiring and fixing problems on boards but I'm not so good at designing without a reference.
With that said I need a particular board. And any help would be greatly appreciated.
What I need it to do is sense a power connection with a light connection then turn on another with a different power source.
Here is a diagram
(THE PERIODS ARE FOR SPACING)
.......<Light>-----<Splice>---------- Positive Cable / On a bus fuse
..............................|
......................<Power sensor>----- Positive Cable / On a different bus fuse to power a second light
............................./
............<Light>----
The reason is that I am trying to wire in a brighter backup light for my truck because my windows are tinted and I can't see it at night.
So I don't want to overload the Amperage on the fuse for the reverse light.
Some may say to just up the fuse but I don't want to do that.
Because I also want to add this to my boat trailer.
But I was wondering if this might be too simple and short out.
That's why I was wondering if there might be another way.
Maybe a more protected circuit?
The thing that I was going to use it for is a Xenon light set.
It takes up to 55W
12V and (10amps max probably for startup) runs between 7-9amps
I just don't want to reach my limit on just the reverse light.
Basically, all you need is a 12V relay, a diode, a fuse, and some wire. You need to make sure that the fuse, wire and relay are rated to carry the current required by the added lights.

I want to have both lights on.
A relay might be easier but I I just want a single coming from the primary light, not two.
With a transistor it would do it that way I want.
Please I need help.
With a relay you only need one connection from the "primary light" to the coil. The other side of the coil can go to chassis ground. I thought this was clear in the diagram I posted: **broken link removed**
Yes you did I was just a little tired when I wrote that and was thinking that you wanted it to go back to the light.
It looks great and when I get my lighting I'll put it in thank you very much.
