I put the GENNSI LED in the 2015 reflector and the results aren't very good on low beam. Sorry for the poor pics, but hopefully you can see enough of the beam pattern.
There are two big problems with the GENNSI LED in the 2015 housing:
- The low beam is blocked by the large hump around the lower running light, leaving a giant shadow in the bottom center.
- The light distribution is much narrower than the 2015.5 reflector, due to the space taken up by the side LEDs in the housing.
The high beam pattern in the 2015 is a little narrower than the 2015.5 reflector, but looks fine. The LED makes a huge improvement over stock.
Apart from these issues, the light output is still very good. But if you have a 2015 reflector, you'll have to decide if the low beam pattern is any better than what you have now.
