Do these lights come with wiring harness adapters or do I need OEM plugs?

These units are designed for OEM fitment, so they'll use your factory connectors. No additional harness should be needed — they plug directly into the existing tail light sockets.

Are these DOT legal for street use?

They're built as direct replacements for factory tail lights. Street legality depends on your local regulations — check with your DMV or local authority before installation, especially since the smoke lens may affect brightness perception in some areas.

Do I need to remove the bumper to install these?

Access varies depending on whether you need bumper removal — that's determined by your vehicle's design. Test-fit from the trunk side first to see if you have room to work without full removal.
