Installing led light in a toolbox

[LSUTiger]

I have a tool box installed on the front of my RV. I would like to add a light in the toolbox hooked up to the house battery. Can I just put the light on a toggle switch >connect the positive and negative straight to battery with the appropriate size fuse and I am good to go or does this have to be grounded some kind of way?

That will work, just make sure the LED fixture is made for 12V.

Flybob,

Is it essentially grounded because the negative side of battery is attached to frame?
