Do I need to replace the bulb, or does it come with one?

The assembly ships without a bulb installed. You'll reuse your existing bulb or grab a replacement — standard H11 or equivalent depending on your vehicle's original setup.

Will this bolt straight into the factory mounting points?

Yes. This assembly uses the original attachment locations — no drilling, brackets, or adapters needed. Hand tools and about 15 minutes get the job done.

Do I need to prep or paint this before installing?

It ships ready to install as-is. If you're matching a custom finish or prefer additional prep, that's on you — but for a direct OEM replacement, unbox and bolt on.
