Will these bolt directly to my factory bumper mounting points?

Yes—these mount at factory locations with no drilling or modification needed. Use your existing hardware and fastening points.

Do these come with bulbs installed?

These are lens and housing assemblies. Bulbs are not confirmed as included, so source and install your own to ensure compatibility with your vehicle's electrical setup.

What's the best way to prep these before installation?

Clean the mounting surfaces and factory locations thoroughly before fitting. Inspect lens fit and alignment before securing with fasteners.
