Will these lights work with my truck's existing wiring?

These mount at factory attachment points and use standard plug-and-play connections. No cutting or rewiring needed — they connect directly to your factory harness.

Do I need to remove the front bumper to install these?

No. These bolt directly into the headlight cavities using factory mounting locations. You can do this without removing the bumper.

Are bulbs included, or do I need to buy them separately?

The LED DRL strips are built into the assembly. You don't need additional bulbs — just plug them in and you're set.
