Troubleshooting Wireless Tow Dolly Lights Where Only Left Tail Signal Works

Question:

Have a set of the wireless tow lights that only the left tail light comes on and nothing else. No signals or brake lights. Have had it plugged into separate vechiles with the same results as well as changed batteries

You've narrowed the problem down to being the wireless tow lights since you've tried them in a few vehicles with the same result. The easy solution would be that there's corrosion on the pins of the 4-way connector which is preventing the circuits from working like they should which would easily be fixed by taking sandpaper to them to clean them off. If it's not that though it's most likely an internal issue with the transmitter or the lights themselves.
