2016 Subaru Crosstrek Custom & Factory Fog Lights

Wasn't sure if they'd fit a 21 since the customer service rep mentioned they did not. But they totally do. I just used a step up bit to cut mount tabs the same size as the OEM lamp to utilize the OE hardware. As far brightness goes, it's day and night compared the joke of a foglamp Subaru offers. Not sure what the last review was complaining about, but these are plenty bright. Just need to be aimed as they came directed a little low. So if you're on the fence just do it! Install took about 30 mins for both lamps and I only had to loosen the lower fender liner to access and replace.
