The running lights are NEVER connected to the converter in normal operation. The only way the running lights will see "converter voltage" is if the owner jumpers the 7 pin umbilical to cause the running lights to burn when at a camping site.
Granted, the tow vehicle alternator will likely put out 13.6-14.2 VDC depending on the charge state of the vehicle main battery, and that voltage could be sent to the running lights, but with the length of wire from the vehicle voltage regulator to the 7 pin plug, the voltage drop would likely only deliver 11-12 volts to the running lights.
ADDED: In the first post, the OP added two photos. The second photo is of the light assembly with the lens removed. The screws are corroded, indicating that there has been water intrusion under the lens. Looking at that same photo, there is a "weep hole/pry hole" to remove the lens. It's mounted at the TOP of the light base assembly and is "covered with silicone"... That "weep hole/pry hole" should be at the bottom of the light assembly, not the top. It's clear to me that the light assemblies were installed upside down at the factory and the silicone plug applied to the weep hole/pry hole failed or there is also leakage behind the light assembly.
As the OP stated in a later post, he is aware that the lights were installed incorrectly and he is replacing them. That should solve the issue as the wiring is likely intact and not damaged. Once the replacement lights are properly installed with sealant behind them, the weep hole/pry hole on the bottom and the lens installed correctly, his problem "should be" solved. Hopefully, his dealership will pay the cost of replacement lights (available at WalMart for $4 each) and hopefully that will complete his problem with a satisfactory result.
