I had asked above what justification there might be for spending $700 (or $560 if you get the 20%) for LED's over the HID's which cost about $118 (Xenonlink.com and others). I assumed there was a significant difference in electrical current draw with the LED's having the advantage. Apparently not.
The JWSpeaker website mentioned by moscooter above has some good information here:
10 Reasons to Upgrade Your Headlights to LED. They are trying to convince you to go with LED's, of course.
That link is a PDF showing a comparison of LED, HID, Halogen and Incandescent lights. It claims LED current draw is only about 30% less than HID's which are very efficient compared to Halogen or incandescent lights. The only other significant, claimed advantage is in color. JW says their LED's are 7,500 in color. My HID's are 6,000 but no one who looks can see a discernible difference. I spoke with Mary in sales at JW. They are prohibited by their contract with HD from marketing their own brand. They have, however, dealers marketing 7" and 4.5" round LED's which would fit the CVO Ultra....
At Street Vibrations, I spoke with the reps from Kuryakyn about LED headlights for the Road Glide. They are awaiting DOT approval. The cost should compare to what they have already done for the Ultra, about 60% of HD cost.
Last week, I rode with Treeman from Mariposa, CA to Miller's Landing (Bass Lake) in the dark. Treeman has an Ultra Limited with LED head and passing lamps. It was about 50 miles on very dark, winding roads. On the road, neither of us could discern any lumen difference between his three LED's and my two HID's. My beam pattern was wider but that could have been due to how his were adjusted....
