Both headlights out
Happened before and against my better judgement I bought two new bulbs and replaced them and low and behold they worked. Didn’t make sense why both would go at the same time. Happened again with headlights and taillights- replaced them all and they all worked.
this morning both headlights are not working- pretty sure I can do the same thing and they will work but what would cause them to go at the same time? Marker lights and tail lights work so I may just replace the switch. Looked at the tech folder for some ideas as well.
anybody have this? 02 7.3

Are the bulbs burned up? Or do they test ok out of the truck? Not sure you could get enough voltage out of the system to burn up bulbs. If you have a meter or gauge, what is your volt reading, is it the same at the headlights?

Pull the socket plugs off at the light bulb and see if they are toasted inside. My wife's Excursion would get a dim light and I would have to get in there and wiggle the wiring at the socket. The first time it happened I bought a new bulb only to find out it wasn't a burnt bulb. I replaced the head lights in my truck with the newer 05+ units and wound up taking the plugs from my truck and putting them on hers...problem solved. I think Dorman makes a replacement that you can splice in...
