Welcome to the forum.Just joined here and wondering about the lack of HID options mentioned.
I replaced the stock bulbs last year with twin HID's with a 4500K colour temp. Which seem to work extremely well here in the UK given the poor climate, and I had already fitted these to my Harley, and previous BMW R1100RS.
I failed at the time to find any LED bulbs in the UK below 6500K and I personally don't like the 'blue' tinge of these. Added to which most of them seemed to be somewhat 'bulky' with large heat sinks. Isn't there also the added issue that blue light scatters in fog/mist/water more than the yellow/red light would anyway, so a lower colour temp would be preferred - least that's as far as I remember from my old physics lessons.
Finally thats not withstanding that at the time LEDs were about 4 times the price of HID systems.
It would help if you posted what motorcycle you have...ST1100 or ST 1300.
