Will this bolt directly into my vehicle without any modification?

Yes — this assembly mounts at factory points with no drilling or panel work needed. Unbox it and install using your existing hardware.

Do I need to buy a matching right headlight, or can I use this one alone?

This is a left-side unit only. For symmetrical lighting, pair it with the matching right-side headlight assembly. Using only one new headlight can create uneven light output.

What's the return process if this doesn't fit or arrives damaged?

Test-fit immediately upon arrival to confirm fitment. If there's a problem, contact ModSupply customer service with photos — we'll handle a replacement or return quickly. Keep packaging for any damaged claims.
