Does the mirror light work without the engine running?

Yes—the light draws power from your vehicle's electrical system and operates independently of the ignition state. Flip the visor down and the light will function normally.

Will this bolt straight in, or do I need new hardware?

Mounts at factory points—use your existing fasteners. No drilling, no bracket modification. Swap out the old visor and secure the new one in about 10 minutes.

What if the mirror light doesn't work when it arrives?

Test the connection immediately upon receipt. If the light doesn't function, document it with photos and contact support within 30 days for a replacement or return authorization.
