Great product excellent price14/10/2016Price, visibility, battery lifeNothing apart from clarification on the aboveResponse of the brandThank you for your question regarding the "legal" point.
To be brief the 320 model flashes but under some laws (and in the UK as well under the RVLR regulations) a steady beam of light must be emitted to conform (there are a few other conditions as well). The 500 model only offers a steady beam therefore conforms fully. In Germany for example, they are extremely strict on this point and flashing lights can not be sold as bike lights. Seeing as we sell throughout the world, the information we provide always errs on the side of caution.
It has to be said that the fine details of RVLR are seldom enforced, and provided you show some kind of white light in front and red behind, it is very unlikely you'll be challenged.
I hope this helps clarify the situation for you.
