Ok I have now managed to get the mast lights working, after all attempts failed and a lot of head scratching I decided to glue a length of 1mm brass rod down the back of the mast, my idea was to use this to provide the live to the LEDs and the brass mast to be used as the negative. All the LEDs were soldered onto the mast and the live tails were then soldered onto the 1mm brass rod as can be seen in the photo's. Once it was done a quick check for a short and happily there was none so the big switch on and happy day's they all lit up as shown.......So now I'm a happy chappy,
Regards Dave.
