One thing I am concerned with is that the Dinotte 140L that I plan on investing on--for my safety's sake--will get stolen in the urban area I live in. I usually ride from spot to spot in the downtown area of my small city and want to carry nothing inside with me, I would like to just lock-up and go without having to remove a single item from the bike. My ideal situation is carrying my lock key inside, and not a thing more!

Is there a solution that allows me to leave the Dinotte on the bike, which of course will be locked-up, for extended periods--even perhaps overnight? The fact of a battery pack makes it impossible no? Though they are not in the same category as far as brightness--I like the portability of the PB Superflash, it's small enough that carrying it on your person is not a hindrance (sometimes I don't even use a bag, just me and the bike).

Thanks, for all comments. New rider here, still learning, though slowly but surely becoming a "cyclist."

It really depends on the neighborhood how much you can leave on a bike for any length of time. Sometimes I take the saddle bag, light(s), and computer with me; sometimes I leave everything.

The Dinotte doesn't take that long to remove completely, even taking the battery pack -- but leaving the battery bag, in the AA models. Stick a finger under the O-ring, and it comes off. It's almost as quick as unclipping a regular bike light.

Yep. A smaller flashing wide-angle companion taillight would be ideal.
