I've had several headlight failures. High beam every time. Every time on a road trip. I gave up on the high output bulbs because of this.

GZ250s have dual element bulbs. It is highly unlikely that you would have them both fail at the same time. You would have either high or low beam.

I carry three spares. A one headlight and one of each for the front and rear turn signals. You need to know how to change these before you need to do it in the middle of nowhere at night. Even the turn signals can be a problem if you have never done it before. Try it at home first.
