I have replaced the bulbs and put the expensive

Older Ford Super Duty Trucks, circa 2000, have current limiting resistors and small gauge wire in their wire harness for the headlights; especially Canadian sourced trucks. You'll have to upgrade the harness. I'm not sure if this was required in Canada or just Ford trying to save a few bucks on the headlight electrical system, but it is a widespread complaint as the headlight output is pathetic. Here's a link to an improvement with some additional info about Canadian DRL.... https://puredieselpower.com/ford/9007-headlight-heavy-duty-wiring- harness-upgrade.html
