The lights I installed are 6 element LEDs and I mounted them on the side-facing end of Lumalink light brackets.
The LEDs are from XKGlow, part no. XK084001-2, and cost $12 for a pack of two.
Here is a link to the kit:

They install nicely with small angle brackets (included) on the end of the Lumalink, and I wired them into the 12V circuit for the PIAA lights.

Here is what they look like in operation:

Does anyone know more about the legal issues surrounding these lights?
