I discussed your issue with both my in-house installers and technical support at Roadmaster and they both came up with the same concerns. It is likely moisture and/or corrosion at the multi-pin connector at the front of your Jeep.

I have attached a picture of a typical connector and would like you to note that it has a plate that attaches with 2 screws and a rubber boot behind it. If you take off the screws and pull it out, then pull the boot back you will expose the area where the individual pins are connected. In there you must eradicate any moisture or corrosion you find. If any moisture causes a short between pins you could have the problem described.

It would be worthwhile to inspect the connections at your tail lights as well. Since it has been working correctly for a while it is unlikely to be that your inline diodes are backwards and allowing any back feeding into the system.
