You may have a short in the switch, if a fuse is blown then your lights will not operate.

Yes, it could be a fuse problem, but if it was random (and not connected to you using your directional signal), it could also be a relay. Both are easy, and I would check fuse first. Disconnecting the battery and having the problem stop, tends to lead me toward a relay. You can check the manual to see which one covers these lights.

Maybe a short or a bad switch...
