http://www.aliexpress.com/item/FREE...t-Cree-Emitter-15SMD-5050-LED/1484795713.html took about three weeks. the difference is better than shown.. there is a focused backward beam from the main led, and the pic is taken from above it. compared to the white, the yellow of stock looks positively sickly. two torx screws and the tail light assembly pulls off two pins, straight back. very happy with the difference.
