@Foxy25 my thinking is that they are maybe a bit longer/wider than all the other models, but in reality these should have been made for the 2016+ CX-9.
they look nice, wish this was standard on the GT/Signature trims.
Btw, has anyone ever bought anything from bamwholesaleparts.com? Their prices are pretty good

price for the bumper trims are $339.27
I installed the same ones you ordered on Amazon, and I think we got the updated version since @sm1ke's looks different. In any case, they fit perfectly in the housing. In regards to the front turn signals, they are already LED.
@sm1ke thank you so much for this. Regarding the bulbs, did you do some research on the brand of bulb? I know there are a ton out there.
Edit: Would it be too much to ask if you did a video guide as well?
