Will these mount directly to my truck or do I need brackets?

These are designed for factory mounting points on the cab, so no custom brackets needed. They drop into place where your OEM lights were.

Do these come with wiring harness and connectors?

The lights themselves are included. Wiring and connector type aren't specified — confirm your truck's cab light harness before ordering to make sure it's compatible with standard LED units.

Can I use these to replace broken factory cab lights?

Yes, if your factory lights used the same mounting configuration. The amber LED output is brighter and more durable than stock incandescent, so they're a solid direct replacement if fitment matches.
