Hopefully you are actually referring to a Vector VEC060 Power Inverter 175/350 Watt DC/AC as I cannot find a listing for a Vector 350 in the flashlight or spotlight listings.

The external fuse for the Vector VEC060 Power Inverter is a standard 30A spade type fuse available at any auto parts store. If you would prefer to purchase online, here is a link to them on Amazon:

Sears do exactly what you need (HQRP AC Adapter Charger ), see Link. Sears com

You can try it online on either eBay or Amazon this can might help you out.

You can order it from Black and Decker, Vector sold all their product lines to them in 2006 and they carry the replacement battery cheaper than anywhere else I found.
