If you want/need a compact light that doesn't take up a lot of space in the cockpit (on the bar) this is a really good choice. Along those same lines it is very easy and quick to get on and off the bar which makes it versatile so to speak and fits all three of the bikes I have very easily. Very good run times that seem to hold up to their ratings based on my use.
I ride a race bike on semi-rural roads in Northern California and use a both flashing taillight and small rear view mirror attached to my glasses. Occasionally oncoming cars will enter my lane to pass and it's clear they either don't see me or don't care that I'm there. This light addresses the former drivers. It is quite bright even in sunlight. It is also small and virtually weightless. My mirror saved my life once, so I am aware that there are.both homicidal as well as distracted drivers out there. This light helps minimize the threat from the latter.
good option to run during the day and be visible... good light power
