Light failure in the dark. P*****g down and no back up. 2 Hour walk down a hill. Never ever again!
I feel for you. My new p7 light decided to start cutting out in the snow today. Luck was closer to home though..
Mine was my front latex innertube exploding of its own accord at the very very end of a ride across Anglesey. I went from near 30mph downhill with a tailwind, to sliding on my left side to a stop on sharp new north Wales tarmac. I skinned my left side from shoulder to ankle, and ended up missing a good couple of cubic inches from my elbow. I wasn't wearing a t shirt coz it was a damn hot summers day and was told that under the missing skin, my shoulder had been given the equivalent of 2nd degree burns. Long time ow.
