Had same problem found light switch had rivited buss bar connections with high resistance at the rivits. Flooded the connections with solder using a high wattage soldering iron and heating issue was gone. It would trip the internal circuit breaker for the headlamps shutting them off! Some warmth in switch is normal, not what you describe. Took me a while to figure that one out. Pushing 60k with no repeats.
