      It was only when I looked to see if these lights only flashed I found out they are to be only mounted on the left hand side wich is no good for the uk and not to be fitted to a bike with disk breaks. They don't work once they have mud on them.
      none of the info was on the box if I had knowen this I wouldn't have wasted my money
      Response of the brand
      Dear sir,
      Thanks for your feedback. I will pass all of this on to the product manger at b'Twin. Your comments are duly noted.
      The fact they they don't work with disc bikes and they mount on the left hand side is highlighted on the website but as far as I can see this is not as clear on the packaging.
      I the meantime, please return them to us for a refund.

      I bought the similar SL200 lights. Potentially a good solution for a city bike but with some downsides that should have been highlighted on the outside of the packaging:

      1. As mentioned on other reviews only designed to fit on the left-hand side of the bike and therefore not suitable for the UK. I was able to improvise by reusing mudguard bolts to fit them on the right-hand side but would not be possible on many bikes.

      2. The lights only work (and in flash-mode only) when the bike is moving and they are quite low to the ground. So probably would need to be supplemented with some other lights for many people.

      3. Instructions could be clearer. e.g. the front and rear brackets are different but this is not mentioned in the instructions. Would have saved me an hour of confusion and trial and error....
      Fit once (eventually) and forget (no batteries)
      Lights only flash when bike is moving
