Will this bolt straight in without any modification?

Yes — this assembly mounts at factory rocker points with no drilling or bracket adjustment needed. Your existing hardware will secure it.

Does the bulb come installed?

The assembly ships without a bulb. Your existing bulb transfers over, or grab a standard replacement from any parts store.

What's the return window if it doesn't fit?

Test-fit before final installation — factory fitment is guaranteed, but always verify alignment before driving. Reach out through your order if there's an issue.
