Do these bolt straight into the factory mounting points?

Yes. These use the existing holes and fastener locations — no drilling or bracket fabrication needed. Harness connections also align with OEM connectors.

Will I need new bulbs, or do these come with them?

Bulbs are not included. Your existing bulbs transfer directly from the old housings into these assemblies, so you only buy replacements when they actually burn out.

What's the return process if they don't fit?

Test-fit before final installation. If there's a problem, contact support within the standard return window with photos of the fitment issue.
