Just been released:

The LED insert is much safer than the standard tail-light. We have worked with Ecliptech to produce a low cost insert that bolts in in a few minutes to replace the bulb with an LED panel, that gives the safety and redundancy of multiple LEDs instead of a single filament.
The LEDs on the front of the panel are pure red dual brightness LEDs that give a light output superior to the stock bulb, but are still roadworthy. There are three ultra white LEDs on the rear of the panel to provide number plate illumination on the XB models that use this feature of the taillight assembly. We cannot find a camera that can show the pure red without some yellow. There is no yellow in real life. The image here has been colour equalised so that it looks more like the real insert. Check out
http://www.eclipze.com.au/bbl/main.html to see images that have not been processed. Remember the yellow shown in those photograhs is actually pure red.
The LEDs are wide angle. They can be seen all of the way around to the side, way better than the bulb is seen. Again better visibility and better safety.
With a design life of around 10 years, these inserts can easily be more cost effective than the periodic replacement of the lamp housing and bulb. The boards are coated and have a high resistance to weather and dust. The LEDs have been placed to match with the indentations in the tail light lens. The quality is first rate.
The designer has a PhD in automotive engineering, and has significant industrial experience with major motor vehicle manufacturers. Ecliptech has been successfully producing LED taillights for motorcycles for the last 4 years. This Buell XB insert is their latest version.
It is simple to fit and includes clear instructions. The wires are colour coded and clip straight into the existing wiring.
3 versions are available. Classic - which imitates the bulb, except of course it is better. The Halo - which is a ring around the edge with extra LEDs in the middle that light up when the brake light comes on, and the LED-X, which is an X pattern across the lens. All three look fantastic with a clear lens.

The packaging states XB12X, which needs to be corrected. The Uly has a different housing and it seems that it has LEDs already.
I have posted the details on the Member Offers Topic
