Ebay is fine, never had any problems.
Those angel lights are not available in shops and prop wont be for a long time. The guy that makes them only makes the rings, you have to pull your light apart yourself and fit them. I've heard that because the saxo has the silver reflective stuff inside the headlight unit, these "angel eyes" wont work very well because the light will be reflected about and will ruin the image of the circle.
Thats the word on the street anyway.
