thanks for the info above, I did try a relay once on my SUZUKI FREEWIND 650 when I fitted twin lights, I did it as instructed by someone who said they knew, unfortunately on one ride to work it flattened my battery so I'm dubious about doing it again, especially as I don't understand electrics 
 ,
I did a quick test today by unplugging both bulbs and fitting an ordinary halogen in one of the lights, I plugged it in but left the other unplugged (so not to blow fuse), with the halogen in place and high beam switched on both low and high filaments were lit, putting an LED back in and it was back to only high beam or low beam and not both at the same time,
as far as heat goes there was a massive amount of heat in the halogen bulb after being 'lit' but the LED was still cool after being lit, I will have to wait and see how they go on a test ride and whether they pass an mot (which ran out today),
I couldn't do anything today as we had a power cut all dayÂ
, was hoping to get the horns done
