Will these plug directly into my factory wiring harness?

These mount at factory connection points, but wiring compatibility depends on your vehicle's harness. Have a wiring diagram ready and test your connections before final installation to ensure proper function.

Do I need to remove the bumper to install these?

Access method varies by model year. Some bolt-ons allow tail light removal from inside the bed or cargo area; others require bumper removal. Check your vehicle's service manual for the fastest approach.

Are the LED bulbs sealed inside or replaceable?

LED modules are integrated into the housing design. If an LED fails, the entire assembly will need service—they're not user-replaceable like traditional bulbs.
