wig wag system for horn?

Sorry for my english here : I'm trying to come up with a 12 volts circuit that would allow me to alternate two car horn at the push of a button. Kind of a wig-wag system but horn replacing the lights... (usually called a "Attention-getter") I've heard about using a flasher and a relay or something like that... Any idea how to proceed ? a diagram would be good ==Skampy4ever==

A 555 or any astable circuit with its output driving 2 relays; one with coil to +12V the other's coil to GND. The output has to be capable of sourcing and sinking the coil currents.

Noting that some (older...) flasher cans require a high load (eg, 50W) else may not flash. But it's easy enough to try...

might try the second one thanks :)==Skampy4ever==

You're Welcome... And I think that your English is pretty good, especially after someone says" Sorry for my English"...M.E.C.P & First-Class

Another questions here... Would it be possible to modify the flashing rate by using some sort of a potentiometer or something else ? So I would be able to make it alternate faster or slower.==Skampy4ever==

No - not if using a flasher can. But yes if using an astable timing circuit - eg, a 555 timer etc.

So how would that work ?==Skampy4ever==
