    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?

    I got water inside both of mine and emaile B&M ot ask how I could take them apart to dry them, they took a while to answer but came back with a very polite apolgetic reply asking me to send it to them for replacement.
