Does our horn have 12vdc lead?

I'm trying to use the horn to trigger a siren.

The wire going out from the fuse box is supposed to have a 12 volt current that activates the horn . Just get your self a test light or multimeter to probe it while the horn is blowing and see if you either get light or right at battery voltage . You should be good .

Retested the horn lead at the horn, and indeed I got 12.4vdc.

Thanks for the help.

I like having an air horn. I've had them on several vehicles and never abused them but when you need to make your prsence known they are dam handy! Especially since no one pays attention these days to what is going on around them.
The problem, is the fact that people are so intolerant these days any legitimate honk of the horn is gonna get ya the finger! Oh well!

I went back and read the original post. I didn't detect any arrogance or idiocy. Huh, must be me.
I like the laser idea!
