Will these plug directly into the factory wiring harness?

These mount at factory cab light locations. Confirm connector type matches your truck's harness before installation — some may require simple adapter harnesses available separately.

Do I need any tools or hardware to install these?

Installation uses factory mounting points, so drilling or additional fasteners aren't needed. You'll need basic hand tools to remove trim panels and disconnect the original lights.

Can I return these if they don't fit my truck?

These are designed for 02-07 Silverado and Sierra trucks. Before finalizing your order, verify your truck's year and model match — fitment issues may result in a restocking fee.
