My grandaughter has a 2011 Ford Fusion that is on it;s second low bean pigtail replacement, The correct bulb has been used as the first was oem and the second was a 50 watt Oreillys.
Either follow the ground wire and make sure it is clean and tight, or run a separate ground wire to the pigtail.
Thank you. I may run an additional ground wire to be sure it is grounded
When I worked for Ford we were always running new grounds for headlights, the stock wires were just too small of a gauge.
