The light in the photo below, I carried that in my handlebar bag for five weeks on my Canadian Maritimes tour, and never used it. No batteries, it plugs into my USB powerbank for power. Strap it onto handlebar with elastic to use. It is for emergency use only.
That light makes some sense since you are carrying the battery bank anyway.
One thing that made me think about is that I could go the other way and use my helmet lamp/handlebar lamp as a battery bank if I wanted to. Primary use on tour would be as a battery bank, it could be used as a headlamp in a pinch. Mine was bought for night time trail riding and it works well in that role. I am pretty sure it would do fine charging my phone or ther devices a few times per charge.
