I have an LED Angel Eyes kit for sale, the kit is designed to fit the original E39/E38 headlights and is complete with LED Angel Eyes rings (white light) and all wiring and relays. The rings are extremely bright and can be seen in daylight.
This is the same kit that many on Bimmer Board have installed, the lack of written instructions is the only thing negative about the kit. The Angel Eyes rings are LEDs, the power draw is minimal so the setup to trigger the Angel Eyes on can be taken off any of the other lights with no fear of damage or excessive current draw.
My intent was to use the instructions below to dismantle the headlight assemblies, clean the inside of the lens cover and install the rings on each of the lights but sadly they don't fit the after market headlights that were installed by the previous owner of my car.
The price is $60 firm, pick up in the GTA only.
