Bright Headlights for Duster - Where can I get some!?!?
Mopar lighting harness barely supports the old low watt factory installed headlights. New high output lighting requires upgrading lighting circuits using relays, and larger gage wire.
Dan can help you with the task, it’s easy, and his site has directions, and diagrams how to go about this upgrade. I made this change to my 1967 Dart last winter using Dan’s parts; big improvement just from wiring improvements.
