Do these plug directly into the factory electrical connectors?

Yes — these mount at factory connection points and use OEM-compatible wiring. No rewiring or harness adapters needed.

Will I need to aim or adjust the beam after installation?

After mounting, test your beam pattern at night. Most factory-mount replacements require minor vertical or horizontal trim adjustment at the mounting bracket — refer to your vehicle's service manual for specific adjustment procedures.

Are these units sealed against moisture and road debris?

LED housings are built to withstand typical truck duty. For maximum longevity, inspect the seal periodically and avoid high-pressure washing directly into the lamp housing.
