Great price. Great fit. Would buy again.
Fit well enough, needed to sand a little for a better fitment. Was not difficult in any way.

Lightweight but so is the original
When the package arrived it was in a very thin lightweight box that was crushed on one side. I thought for sure it was trashed. By chance…all was good. The lights are thin plastic but made very close to the original standard. They fit well on the car but the gasket needs to be tucked in around the edges. That material seems thin. The end result is actually a nice looking inexpensive light. Overall I am happy.
