Do these bolt to the factory bumper mounting locations?

Yes, these mount at the factory points — no drilling or fabrication needed. Confirm mounting tabs align with your bumper before final fastening.

Are the wiring harnesses included, or do I need to source connectors?

The units come pre-wired. Verify that your vehicle's factory DRL harness matches these connectors before install — some model years may require an adapter.

Can the smoke lens be painted or modified if I want a different finish?

The smoke tint is integrated into the housing. Painting or sanding it will change the appearance and light transmission — test in a hidden area first if you plan any modification.
