Thank you kindly gentlemen,
I think I have resovled the issues, the contacts arent great.
Checked the charger and yep pushing out a healthy 8.4vdc.
However did buy a multicharger , and charged it on that, just turned the light on and leaving it for 15 mins to see if it did charge.
We dont have drink driving here, so anytime after dark is crazy , that and everyone is driving american metal everywhere. mack trucks, big chevy's and lincoln's etc.
That didnt work for toffee, indicator on rear of light just came on red :( will try everyones advice .
Again , thank you all, have a good christmas and new year :)
