I put a similar one on in 2010 when I was building mine, mainly because my bike was charcoal/silver and red stuck out. The OEM was brighter, but it worked as intended and felt safe using it. I didn't hook up the integrated signals on any aftermarket gen 2 tail light, never understood why they even put them.
Also ran the smoked with the full LED board, down side was the LEDs were at a 45deg angle so not as useful as it should have been. I found a broken OEM tail with no lense on ebay for $20 and got it and swapped the smoked cover on it and best of all worlds IMO.
