2007 Yamaha Road Star Midnight Silverado headlights, tail lights, and speedometer lights are not working. Is there a fuse and where is it at?

Try looking at the electrical schematic at the link below, just choose your specific model.

The cover under the sear has one allen bolt. on the left side take off that cover and there is a fuse box with blade fuses in them thats the only place to check fuses if fuses aren't a problem check the connections in the wiring harness and make sure there not loose.
