Will these bolt directly to my stock mounting points?

Yes—these are designed for factory mounting locations. No drilling or panel modification required; you're installing into the existing fascia openings.

Do I need to splice into the factory wiring harness?

The switch is pre-wired into the assembly, so you'll integrate the harness at the factory connector points behind the fascia. Specific wiring routing depends on your vehicle's interior layout—review your service manual for switch placement options.

Can I swap out the H11 bulbs for a different color?

H11 bulbs are standard aftermarket parts—you can replace them with other H11 options in white, blue, or other tints. Just verify the bulbs you choose are street-legal for your region before installation.
