wiring headlight help

I recall being on a very dark street when my headlights suddenly went off. 45 seconds maybe, the time it took to come to a stop and think WTH? They came back on. Happened a couple more times before I covered approx' 6 miles to home. Glad factory circuit protection is a cycling circuit breaker and not a fuse. New headlight switch cured it. If my memory serves there was no other fault found.
The draw of relays coil might never open that breaker so we've already bypassed/forfeited that feature.
I have agree with completely separate independent circuit for all those other lamps/fixtures, like factory. Just too many places for a fault to happen and take out all lighting. Although... brake lamps, turn signals, hazard flashers, might still work depending on where the fault is.
