Do these headlights need any special wiring or will they work with stock wiring?

These mount at factory connection points, but the sequential function requires integration with your truck's wiring. Consult your vehicle's electrical schematic or have them installed by someone familiar with headlight harness modifications.

Can I return these if they don't fit right?

Test-fit before fully securing. These are designed for factory mounting, but slight variations in body panel fitment can happen. If alignment is off, reach out before permanent installation.

Are the LED bulbs replaceable if one burns out?

LED units are typically sealed assemblies. Check with the manufacturer for service options if a light fails—most won't need replacement for years, but having that info upfront is smart.
