Do these lights come with bulbs installed?

The assemblies are complete units. Confirm bulb type and condition before installation by testing power at factory connector points.

What's the install process?

These mount at factory points — no drilling or custom brackets needed. Unplug the OEM lights, pull them out, and swap in the new assembly. Reverse the steps and test.

Can I return these if they don't fit?

Test-fit before sealing anything into place. These are designed for factory mounting, but physical verification on your vehicle is always the best confirmation.
