Vya Switch is the latest addition to the Vya Family, foregoing auto on/off technology for a traditional button design. Why the new design? Light and Motion had multiple requests from riders who loved the power and simple effectiveness of their Vya taillight but wanted to adjust runtime or change to a solid mode for group riding and bike path commutes.

The button control also allows cyclocross and mountain bikers who hit pavement en route to the dirt the ability to turn the light on/off as needed. There are also the purists who are so accustomed to manually turning their lights on and off that not doing so creates that 'Did I Forget Something?' feeling. Yes control freaks, Vya Switch is for you!

    Great light but doesn�t fit aero post well.
    by DWPDX

    For the price, this is a very bright light. Rechargeable is key. I typically put it on the lower setting for daytime riding and it�s plenty bright.

    My aero seat post is too narrow for the light though. So the light would rotate left or right when I hit a bump and I would have to adjust it.

    I tried cutting a piece of PVC as an adapter which helped some, but still rotated some.

    I ended up getting an adapter made by Giant for a few bucks that works well. I�m not sure if the Light and Motion adapter works or not.

    Stopped working after 3 months

    I ride to work every day in the PNW, so it is dark in the winter. This was a great light for my commute, lightweight, bright, charges quickly. However, it just stopped working after 3 months. It did not cost very much ,so I guess one season light for the price was not that bad.
