You have it absolutely right; if your turn signals are not working when you turn on your headlights, the issue is a weak ground. It is possible you may want to consider switching to lights with a separate ground as opposed to your current lights which sounds like ground through the mounting hardware. This way you can ground them to the steel trailer frame as opposed to the aluminum mounting hardware. I have added a link to our selection of trailer lights for you so you can find ones with similar dimensions to use as replacements.

I have added a couple of cut outs from a help article I linked for you on troubleshooting trailer wiring, and I highly recommend reading this guide.
