This is what I do with my helmet-mounted light (I also cover my bar light with my hand). It generally works out OK, except for those rare times when I've got walkers/runners on both sides of the trail (yeah I know they're only supposed to be on one side, but that's a different problem), or a walker on one side and an oncoming biker on the other; then I just try to keep my head pointed down as much as possible.
Edit: I do not have a 3200-lumen helmet light. If the ad copy is to be believed, I think mine is about 1200 lumens max, but on the unlit MUP I find the low or medium setting more than enough to light up the wildlife, upcoming turns, "road" hazards, etc. Once I'm back on the streets I generally turn it up a notch or two so I can use it to "light up" inattentive drivers. My handlebar light is rated at 650 lumens, but that too I generally run at low or medium on the MUP; once I get on the streets, it goes into "look at me" strobe mode, and sometimes up to max brightness as well.
