I just got my 200L headlight to go with the taillight I bought a while back, and immediately strapped it to my bike. I've got the AA version, and I strapped the battery case to the horizontal part of the handlebar stem (not sure what that piece is called). I turned all the lights off in my garage and put the taillight and the headlight on the strobe function. My neighbors found me seizing on the floor soon thereafter. Seriously though, it was like a night at the Roxbury in my garage. I can't wait to get out there in the dark with my new headlight. Dinotte is definitely the way to go.
