Expert Reply:
If your trailer lights are only coming on and working when you are hooked up to your tow vehicle through the ball mount, the issue is a bad ground on your trailer; essentially the trailer lights are being grounded through the hitch ball. You'll need to make sure your grounds are attached to bare metal surfaces and free of any paint, dirt or corrosion.
I have added links to a pair of help articles on trailer wiring, including a troubleshooting guide which I highly recommend taking a look at.
