Will this bolt directly to my vehicle without modifications?

Yes. This assembly uses factory mounting points—no drilling, cutting, or fabrication needed. Slide it in and bolt it down the way the OEM unit would.

Do I need to install a bulb, or does it come with one?

This is the housing assembly only. You'll need to source and install the bulb separately—pull it from your old headlight or grab a replacement at any parts counter.

What if it doesn't fit perfectly when I get it?

Return it within 30 days if there's a fitment issue. Before you install, test-fit it dry against your vehicle to confirm alignment. If gaps are off, contact support before drilling or fastening.
