I can be both sloppy and clumsy and have destroyed several batterypack and lighthead setups. I will ride quite a few miles both commuting and training after work in our very long Norwegian winter so I decided to buy some new lights this autumn. The one light that I have not managed to destroy is a Silva LX, not really meant for bicycling but it has served me well both CX skiing and cycling. However I need more light as the years go on and now I bought an Exposure Lights cordless setup with a Diablo on my helmet and a Maxx-D on the bars. No cables for me to wreck and the build quality seems very good. Lots of light !
