Hi Noel,
Thanks, I am bit weary of connecting anything to the mills PCB's in case of any issues etc. I'll go with a seprate plug in 12vdc to power the LED thus removing any risk to the Mills PCB's. These are avaliable easily from ebay etc. The LED is an SMD 60mm rated at 12v-24v Angle Eye for Automotive so is going be a low wattage rating pos 40ma but havent checked this, fits great on the Mill 
Thanks for coming back me
