Will this bolt directly to my vehicle without any drilling or brackets?

Yes. This assembly uses factory mounting points — no holes to drill or custom brackets required. Line it up with the OEM fastener locations and secure it.

Does the bulb come installed, or do I need to source that separately?

The assembly ships without a bulb. You'll need to install your own bulb into the housing before mounting. Check your vehicle's manual for the correct bulb type.

What if the lens has condensation or the assembly doesn't seal properly after install?

Test-fit the assembly before finalizing installation. If moisture appears inside the lens after mounting, the seal may need adjustment or gasket replacement — contact support with photos for guidance on next steps.
