Will 3w led lights that are for 220v work on a 12v system?

Im doing a camper van conversion and Ive purchased 3w led spotlights and in the packaging it says "disconnect the 220v" so Im presuming they are meant

I'm doing a camper van conversion and I've purchased 3w led spotlights and in the packaging it says "disconnect the 220v" so I'm presuming they are meant for household use on a 220v system.. my question is, will these work ok on my 12v leisure battery system? Thank you
