Do these need bulbs installed?

These are light housings only — you'll reuse the existing bulbs from your current corners or source new ones if needed. Check your service manual for the correct bulb type.

Will I need new fasteners or clips to install these?

Mount at factory corner points, so existing hardware should work. Before sealing anything permanently, test-fit both sides to make sure everything sits flush.

Can I return these if they don't fit?

Contact ModSupply directly with photos of fitment issues — they'll walk you through returns or solutions. Keep packaging and condition documentation.
