Bill, you are correct. The switch would have burned out if not for the earlier circuit breaker install. The switch bimetal strip (on the headlight side) was getting hot and opening/closing. It was very hot to touch. Now the switch is cool as it does nothing once the lights come on. Well nothing to run the headlights, it still runs the taillights and dash lights. The bulbs..?? Dont know how long they will last...and doesnt really matter as I can now upgrade the bulbs to halogen if they fry. The main thing is I now have reliable lights and a safeguarded switching system and protected under dash wires. BTW, the switch is a Delco-Remy, made in USA...not a foreign chepo.
