I just had to learn this circuit myself. My problem is apparently a blue wire shorting to ground between the harness neck connection and the front signals that was causing the fuse to blow.
Dan's right. For some reason the headlight circuit is also a blue wire but a totally separate circuit from the blue wire circuit marked "lights" at the fuse block. The only place the "light" circuit goes is to to the tail light and to the front turn signals. Its one of the simplest circuits on the bike.
Do you have a meter or test light? One is needed to do more than a look and wiggle. The only things you can tell without one are to look at the fuse and if thats really good, the front signals should be lit as running lights, not just working as blinkers.
If you do have one, this circuit is switched so the ignition switch has to be on to test past the fuse block. As Dan said, 1st check for voltage at the fuse block and also make sure your fuse is actually good. Sometimes a fuse will be bad without looking blown. If those check ok, check for power on the blue wire at the harness connection to the rear fender. If you have that, I would suspect the LED ballast as Scmidty said, or the blue wire in between the harness connection and the tail light. If your brake light works the ground is good.
