Do I need to tap into the factory harness or can I run these standalone?

The wiring harness connects to your truck's existing electrical system at factory points—no splicing or T-taps required. Test the connections before final panel installation to confirm continuity.

Will these bolt up to the bumper directly or do I need brackets?

These mount at factory fog light mounting points on your Tundra bumper. If your truck has factory fog pockets, no additional brackets are needed. Verify your bumper has the correct openings before ordering.

Are the bulbs included or do I need to source those separately?

Bulbs are not included with this kit. You'll need to source the correct bulb type for your model year and install them into the housings before mounting.
