Subaru's XV Crosstrek Hybrid, the company's first hybrid vehicle, was slated for a "Fall of 2013" release, though they didn't start hitting dealership lots until late December of '13 and early January of '14. I was able to test-fit one and check a few things out so I could know if it was as easy of a swap as I thought it might be. To the right, both the Impreza and Crosstrek Hybrid taillights are sitting next to eachother. The dirty one is the Impreza one (off my car). You'll notice the points that mount to the body are identical, but the arrangement of the lights is different.
The biggest hurdle is the plug for the lights. There is a 6-pin connector that plugs in to the assembly that has a different shape on each version. The plastic housing for the Hybrid LED Taillight is a different shape, although the pins are in the same place, than the Impreza's housing. They will not plug into eachother in their stock format.

Just another way this Impreza of mine is confusing fellow owners. Quad exhaust? Side skirts but no roof rails? What IS this thing?
