It is a USB chargeable light and supports a strobe mode as well as a few different brightness settings.

Thanks very much!

    Can you take a clearer/sharper picture of the logo? – Vladimir F Apr 13 at 7:54
  • These are the only pictures I have of it. (I've since lost it) – sente Apr 13 at 19:35

Something in the Serfas E-Lume family, possibly a Serfas E-Lume 900.

    Probably not street legal in some countries. – Michael Apr 13 at 10:36
  • @Michael is that true? Can you link to some evidence? Thanks! – JoeK Apr 13 at 10:37
  • @JoeK: As far as I’m aware at least in Germany and Austria the front light mustn’t flash and mustn’t even have a flash mode (hence why you can’t even buy such lights in German online stores). It also must be designed in a way not to blind oncoming traffic, which rules out all the usual MTB lights with circular light beam. I suspect the E-Lume 900 does have such a dangerous beam pattern. – Michael Apr 13 at 11:02
