Has anyone experienced this? I was cycling along in dark, dry conditions. I stopped for a break and then when i started off again the b & m cyo wouldn`t light up. I had to ride home on the emergency lights. Luckily i wasnt too far from home. When I checked the hub dynamo (shimano) output the voltage was good so I stripped down the cyo. On the PCB inside several of the tiny components in the bottom corner had fried and burned out, but I couldn't see why as there was no water or debris ingress. I have had the unit for about 2 years but am pretty sure its outside of warranty. The led still works as the standlight is still functioning. Needless to say I am a bit taken aback that it went like this as I thought that these lights were designed to give many years service. I wonder if the b&m would replace or if they would be interested to see the failure as I bought the light from a supplier in Germany? Also gives me doubts over wether to go for another cyo? Anyone else using a dynomo front light and managed to get more than three years out of it?
