Since you weren't beeping or driving at night, the brake switch is a likely suspect.
Put a new fuse in and hit the brakes to eliminate this possibility.
If that doesn't find the culprit, then do the item by item check, using a test light in line whrre the fuse should be.
It will light until the culprit circuit is found, assuming a short to ground, and the bulb's filament will certainly burn out long before the smoke starts to escape from the harness.
