I removed the ff50 HID's from under the mirrors (they went to a good home on the range) and replaced them with the larger Clearwater Krista LED, (link to the site
http://clearwaterlights.com)
the site will give you all the information on these lights. I also run the Glenda ones on the forks.
I found the LED lights to be slightly better than the ff50's with the HID conversion, more than likely because the light colour in the ff50 was 4300K. The light colour of the LED appeared to me to be the same as the HID spotties which is 6000K. Both the FF50 HID and the LED cover that medium distance to where the HID spots take over. The biggest advantage for me is that there is a lot less power using the LEDs and not using threee sets of HID lights. Biggest disadvantage is the cost
On the FarRide out to Lightning Ridge I heard a comment from a couple of truckies coming the other way and that they thought I was a truck coming towards them
I am happy with the results and the LED lights but not with the price
