Fantastic light for night trail riding in the UK winter works well on its own bar mounted but my go-to setup has been the Allty2000 on the bars and the Allty1000 on my helmet the two go well together and give a huge amount of light without having to run any wires to external battery packs attached to the frame. Magicshine 2018 - 2020 have been releasing some really well thought out products the support is right up there with some of the best. Marc Ride_ya_bike
