Will a relay work?

I have 72 volt dc cart - that when put in reverse - sends a 72 volt positive signal to a buzzer. I want to replace the buzzer with a chime (that can only hande 12 volts). Can I use 72 volts as the signal into a relay to trigger (close) 12 volt connection to the chime?

If so - I am unsure what size relay I need.

Perhaps there is a more efficient way to sove this?

Thanks!

Is 12 V available ? Possibly could use a 120V AC coil relay if 72 V DC is not available, or use 48 V DC with dropping resisror. Contact rating sufficient for chime.

Here is an alternative. It is a solid state relay which is generally better than an electromechanical relay. Max load current is 5A. Do you know how much current is needed for the chime? I can't imagine it being a lot.
