Will this marker fit my existing bumper cutout without modification?

Yes, this is designed as a direct replacement at the factory side marker location. No drilling or bumper cutting required.

Does the crystal smoke finish reduce how bright the marker appears?

The smoked lens dims the light output slightly compared to clear, but it's engineered to stay visible. If visibility is a concern in your area, test it before and after installation.

What comes in the box with this marker?

You get the marker light itself. Verify your vehicle's original mounting hardware is still intact before install — you may be able to reuse the existing clips or fasteners.
