What should I check before ordering to make sure these are right for my car?

Verify the OEM part numbers and the model years listed to avoid buying parts that won’t seat correctly. Compare the shape and mounting tabs of your existing reflector to the product images and part numbers.

• Match one of the listed part numbers: A1668200474, 1668200474, A1668200374, or 1668200374.
• Confirm your vehicle is a GL (X166) 2013–2016 or a GLS450 2017–2019.
• Inspect the bumper opening for any damage that could prevent a flush fit.
• Contact a technician if your bumper has been modified or repaired previously.
