What would be the easiest way to upgrade the headlights on a 389 Pete? If I would of got a 379 I would just of swapped the seal beams for some LED ones but with the 389 projector style headlight, would I have to swap to whole assembly to get better light output? Or get an HID retrofit done? I tried different halogen bulbs from the Pete dealer but I didn't see much of an improvement.
2015 Peterbilt 389 headlight upgrade?
