I'm having light issues as well, my Exposure light has just died. I should be OK with the Dinotte, I normally only use the battery with the rear, but I can add a Y and power the front light with it as well. I tend not to use this, since having the cable running along the frame is a menace, but it's not too much of a problem for occasional use. I think it's rated for 32 hours on low, so even with the rear light draining some of the power, it should be OK for one nights use!
Like AdrianC said, it won't need all that much lighting, You're probably OK with just bog standard road legal lights.
