6V horn on 12V system

Hi guys, I just bought on ebay a really good horn for my chevy 52. It is 6V and my truck is 12V ¿can I make it work anyway?
Thanks,
Alfonso

 

Works great and is LOUD, just don't honk continuously. Same with a 6v starter.

 

Thanks Evan, that means that I can used directly to the 12V?

 

yes you can. i have it done and my horn sounds with 120dB
Loud enough for all new car in front of you
