OK, will do.
For the benefit of all reading this we are talking about an internal break of the copper wire caused by metal fatigue.
I have had this on odd cables with my own lamps and is usually the result of poor routing.
Taking the cable over edges on a tension will cause failure. Tensioning the cable so that its on a stretch against a gland will cause failure. I hear of Scurion cables, now Stenlight, my own, and possible others.
I think that if people wired their lamps around their helmets with the same considerations that they would use to rig an SRT pitch, this might end.
I am just trying to save people having problems here.
Having said all of this, that Chainflex cable is seriously tough, but under tension, I think in time it would also fail. Just take longer.
