Could it be the fuses in the truck?

Could be.... But it could be other things too.

What kinda of truck? What kind of trailer? What type of tow system (OEM or Aftermarket)?

Be more specific...

Are you using Flat 4 wire connection between truck & trailer? I bought a flat 4 wire Key chain tester. If I ever have light issue first thing I do is plug tester into the truck, turn on parking/running lights & hazards. If all 3 light work on tester, then the issue is the trailer (usually bad ground). They probaly make tester for the other style trailer connections but not sure, or a simple volt meter will do to test the truck.

my running lights on my trailer stopped working bu it ended up being a bad ground on the truck and had nothing to do with the trailer...if someone you know has a truck or any vehicle set up for towing plug your trailer into that and thall tell you if its the trailer or your truck
