Will this mount at my factory hood attachment points?

Yes. This is designed for OEM mounting geometry on the VN chassis — you're using existing holes and brackets. No drilling required.

Does the sequential LED require any wiring or power source?

The LED function doesn't demand a separate power harness setup — it's integrated into the manual mirror assembly. Wiring specifics aren't detailed in the product specs, so confirm routing during installation.

Can I use this on both sides or just one?

This listing is for a single unit. If you need mirrors on both driver and passenger sides, order two.
