I'm wishing that I'd got back onto this forum before buying new lights recently: I ended up going for the Niterider Mako 200 USB/Solas USB combo from the EBC.
Whilst I am really liking the rear light, and the front light itself seems fine, the mounting brackets are not at all well designed. The rear one is ok, if just a bit strange, but the front one is awful... I don't know if my bar is particularly thin, but the bracket wouldn't even tighten onto the bar at all until I used a rubber insert that had been packaged with but turned out to be unnecessary for fitting the rear mount. For some reason it tightens into an elliptical rather than round shape, thus still fails to grip the bar effectively even with the extra insert. Just to top everything off, it uses a quick release ratchet so could be lost or stolen easily.
My first attempt at using the lights this week ended up with the front light gradually tilting down each time I went over cobbles under the canal bridges, the forward positioning of the light on the bracket contributing to the tilting as well as the grip issue. I am now trying with the bracket mounted upside-down to try and reduce its tendancy to tilt, which so far seems to be working, although it remains to be seen whether this will limit the waterproofing ability in the wet. One advantage of this set-up is that I am able to mount the front light bracket between bell and cycle computer on the right, freeing space on the left for a phone mount, assuming that I get around to upgrading to a useful smartphone.
