Re: Is a Horn Relay Necessary?
No a relay is not necessary but keep in mind that the horn draws several amps and the switch would need to handle the current. on the other hand the coil of a relay needs very little current and a smaller switch can be used to activate the relay and the relay contacts handel the larger current for the horn.
