Bad Headlight Switch?

Get @crackedback Rob's headlight harness. Best thing I ever did to mine. In short, NO, your stock Mopar wiring and stock style switch are not made to handle stock headlights very well, much less any type of upgrade. You can prove this easily by turning the lights on ans letting it sit about 15 minutes. Reach under the dash and the switch will be hot. That's a failing (one of many) of the Mopar system.....and really all of them for about the same time era. The harness Rob makes uses the headlight switch as a low amperage trigger to fire the relays that handle the load. You also get full alternator voltage to the headlights. That means bright! And yes, if the switch is wonky with the dome light, it sounds like a POS.
