My 2006 f150 Ford front lights and back lights are having issues, I was installing a new stereo and when I finished, the lights worked for 5 hours but then they just stopped working. I checked the fuse #42 and is was burnt out so I replaced it, but it didn't fix anything.

You probably have a grounded out wire some where, pull the radio out and check to make sure you didn't mess anything up. There is a wire there that has to do with the light dimmer for when your headlights turn on the radio dims. Maybe you hooked that wire wrong.

 

And I would also check to see if the fuse you replaced has blown again. That would be a sure sign of a short somewhere.
