Likely headlight switch. If you pull a trailer or have marker or chicken lights, you need a relay on the tail/clearance light circuit after the switch. The after market switches pretty much vacuum. Above said relay and headlight relays will make em last.

If your H/L switch plug is melted like many have seen. You can buy a new socket from Dodge. The pre93 is N/A now. The 94+ you can still get. The plug is the same. There were some color changes on wiring in 94. Just wire the new plug by the position of the wiring on the old one.

Let me give you some back ground info first. I worked in injection molding for 15 years.
The original material for that head light plug was made from Noryl GTX material. That stuff has a melting point of 550 degrees. It is a 30% fiberglass fill plastic.
The O-Reilly's headlight block I had in my hands a few years back was not made from Noryl. It was made from a lower rated plastic. From what I could tell it look like polyphenylene. That has a melt under 300 degrees. If a terminal connection problem can melt a Noryl plastic. The polyphenylene will catch on fire.
BTW that plug is one of the parts we made for Dodge. It was ran in a 220 ton machine with a 30 second cycle time. It made two parts a cycle.
