Do these need bulbs installed?

Confirm whether your originals are bulb-in or sealed unit style before ordering. If your factory lights use replaceable bulbs, you'll swap those into these new housings; if sealed, the bulbs come as part of the assembly.

Will these clear lenses pass inspection?

Side marker lights have specific DOT visibility requirements. These are designed for that purpose, but local inspection standards vary — verify with your state's inspection criteria before installation.

What if the fit is tight?

Factory mounting points are consistent, but trim or bumper variations can create binding. Test-fit before final fastening; you may need to hand-adjust the bumper clips or filing of the mounting tabs.
