Just a thought. I like the idea of connecting the headlight and the driving lights through completely different circuits so that if a fuse blows or some other electrical problem takes out one circuit, I still have some lights to at least get me safely off the road. I neglected that when I rewired all my accessories a few months ago but plan to make that so on my bike very soon. Also, I will be installing a circuit breaker instead of a fuse for the main headlight.
If I was concerned with that, I'd install a 3-pos selector sw to select trigger for a relay, from the blue wire on one side, and the accy circuit (or running lights) on the other. Center post to the relay trigger. That design would power the spots with the high beam ( or you could use the blu/wh wire, which is power to the hi-lo sw to have them on always) so the lights would come on with the high beam, or any headlight with the blu/wh wire. The spots would go out with the starter just like the headlight, which is important especially if your battery is weak - that has been a problem for me several times over the years. If you lose the headlight circuit, throw the sw and the spots are independent of the headlight circuit but wouldn't go off when hitting the starter. Center position on a 3-pos sw would be off.
I have not been concerned with losing the headlight circuit because that has never happened on my bikes.
