Apologies Ben they are not Fiamm but .....

Piaa sport horns 400 hz and 500 hz not air horns so no delay.

Hi Keith
They sound like (pun intended) just the ticket for negotiating the double mini roundabouts at the end of our road where drivers regularly just drive across the second one and ignore anyone trying to turn right into our road.
Did you need to fit a relay?

I'm now slightly spoilt for choice!
Does anyone have any experience of these bad boys? 150db apparently.

They are available considerably cheaper on Amazon.

They look identical to the Steibel ones I posted an eBay link to but with addition of air filter for six times the price! Obviously there is a delay with all air horns using onboard compressor but with Steibel type it's undisernable. Mine have worked perfectly now for nearly seven years.

I use these - got one on the MG, the Morgan and the Harley.

Plenty loud enough. https://www.halfords.com/motoring/car-accessories/exterior-styling/12v-compact-air-horn-678022.html

There all the same generic type. Call them Steibel, Nautilus or whatever. Wouldn't be surprised if they are all made at the same Chinese factory as unbadged items then boxed and labelled for different world markets.

Alan no, didn't fit a relay they draw a combined 5.5 amps. They certainly wake up those idiots who think oh there's an old car coming I'll just wander out in front of it.

Yes as Richard says its an independent circuit and always use diode protected relays in all positions!
There technically is an MOT issue with most Morgans as most fall outside the cut off date allowing air horns to be installed. First thing to check is have you just got one horn fitted behind the grill/stone guard. If so it is probably the low tone klaxon. The car is wired for two and the wires are just taped up, the mounting hole is also there. Just buy the high tone option or a kit with both in and fit the high tone as well. You will be very pleasantly surprised by the difference in both sound and volume and nothing else will need to be modified to fit this addition.

That's what I did, original was useless.
