Will this require modifications to the front bumper or mounting points?

Mounting points are designed for factory-standard locations on your Highlander. Test-fit before final fastener selection to confirm alignment with your specific vehicle condition.

Do I need bulbs, or are they included?

Bulbs are not included with this assembly. You'll source them separately based on your preferred brightness and color temperature.

Can I install this myself, or do I need a tech?

The wiring harness and switch are pre-assembled, so most of the electrical work is already done. Mounting and final connector routing are straightforward if you're comfortable with basic hand tools and have a working knowledge of your vehicle's underhood layout.
