So my wife goes to get in our '16 outlander this morning and the taillight is smashed and on the ground. Not sure how.

Call mitsubishi and it's 575$ for the replacement assembly.
Highway robbery.. can't find anything aftermarket for it and no local parts stores list anything.

Sounds about right for a headlamp/taillight. Try a scrap yard?

Yep. Nothing.

I mean I'm sure it'll be a tough find but it doesn't have to be a 2016 one right? Current gen Outlander is ~5 or so years old a scrapyard in the country must have one if you could find one and have it shipped. But that could be more effort than it's worth.

Nah its only 14-16 for this body style.

I'm waiting to hear from insurance if I can get it considered a hit and run they wave my deductable and it's a no fault accident.

goto dealership and ask for a pair of them

"accidentally" drop the one you don't really need

get a discount because they now have uneven pairs of taillights

You gotta be careful. These have rear "fogs" as well and those are dirt cheap. The Tail lamp themselves are pretty expensive from what I found.

Rockauto didn't even have these
