WHAT WOULD CAUSE ALL OF THE REAR LIGHTS NOT TO WORK?
For all of the light to go out I would look at the harness that heads towards the rear of the truck, it could have disconnected itself or you have a damaged harness.
yea what tennisshoes said
I viewed a diagram for the tail lights on my 2010 F-150. It appears all the rear lights function off a single shared ground. Use a multi- meter to check for current to the sockets. If present, look for a bad ground.
Disconnected/damaged wire harness or bad/broken ground wire
