Bright, easily seen, has three modes and easy to install. Got mine with the Ion 1 in a pack for $30. All weather light, has a seal around it. 3 bright LED's, looks like Cyclops from X-Men is about to Optic blast you out.
It's good for being seen, easy install, lasts a long time. I would recommend. It's a tail light, what more is there to say?
