Recommend a horn for my dually?

LOL. Back in the days of the limelight '70, I was "B.O.'ing" down the freeway mindin my own business when some hippie in a VeeDub, pot smoke flowin' freely from the windows, came piddlin' out an on ramp up ahead, wandered across 3 or 4 lanes of traffic on the San Diego freeway, and "landed" right in the left lane doin' about 50 mph.

I mashed on the Warner Brothers registered trademark mee--meep horn a few times until I realized this was having less than any effect.

So I went right down to one of my favorite shops and bought

and THOSE generally got some type of result, not always positive.

NOW the guy (friend of mine, George, K7WWA) who was the previous owner of my 70 RR, USED to have a 65 Chevelle when we first met at Treasure Island in '68. Now HE had a 400 watt AC inverter installed in the Chevelle, triggered through a solenoid hooked to the horn button. The inverter was "by default" plugged into a 120V AC submarine dive Klaxon!!!!

DIVE DIVE!!!! OOOOOOOOOOOhhhhhgaaaaaa!!!!
