GM 13578958 Rear License Plate Lamp – 2013-2014 Cadillac ATS – Outer, Halogen

Need a rear license plate lamp for your 2013-2014 Cadillac ATS?

This GM unit is the real deal—OEM part number 13578958.

It mounts on the outer rear and includes bulbs (D1S shape, cold white), mounting hardware, and a black housing with clear lens.

Halogen lighting, SAE-certified, and a 90-day warranty.

It's new other, meaning it's unused but maybe the box is gone.

No big deal—it's the part that counts.

Direct replacement, so it'll bolt right up.
