Do these bolt straight on, or do I need to modify the bumper or hood?

These mount at the factory headlight points—no drilling, cutting, or bumper work required. It's a direct swap if your truck's mounting tabs are intact.

Will these work with the factory wiring harness, or do I need a relay?

LED DRL headlights typically draw less current than OEM halogen units. Check your truck's existing harness compatibility before install; some builds benefit from a relay harness to avoid flickering or warning lights.

If one lens cracks after I buy them, can I return just that side?

These ship as a matched pair. Return eligibility depends on the condition of arrival and your purchase window—inspect them immediately upon delivery and contact our support team if there's a defect in manufacturing.
