Thanks Dennis and Scott Scott please let me know what to be looking for and documenting
This appears to be the rear marker lens that I found in the car. Both appear to sort of be amber.
Note: The top installed unit only has 2 reflector panels.And it's font is tward it's upper edge, it's much lighter in color
The one I am holding has 4 reflector panels,and is shorter, and a good fit for the rear of the car. It's font is tward it's bottom edge and it's much darker
The cars SPD is 505 cinco DeMayo. I see in Troy's post that they changed during production so hope this helps
