Brake light problems
I have a 2007 F450 Super Duty. The brake lights work but when I turn on the headlights the brake lights do not work. I've changed the light switch on the dash, replaced the pig tail under the dash and replaced the break light sensor that mounts up by the emergency brake assembly under the dash. Nothing has fixed the problem. Im starting to think it may be the break relay but don't want to spend any more money on parts that I don't need. Any suggestions??

There's no such thing as a "break relay".
Go check the ground for the tail light assemblies. Sounds like its open. It's up under the bed in the left rear corner on the frame rail behind the bumper.
