Dual Trumpet Horn Failures

[Kickman921]

I replaced the electric Dual trumpet horns on my 2005 dolphin LX a year-and-a-half ago because the horns that were on the motorhome when I purchased it in 2015 didn't work. Now the five oceans Dual trumpet horns from which were Maritime horns rated for saltwater and harsh environments failed. I took them apart and one horn had corrosion the other horn actually had its contacts soldered together so my question is what brand of dual trumpet horns would you all recommend?

I also considered mounting them in the engine compartment where the current snail horn is mounted, it would protect it from most of the elements but my concern would they be loud enough to the effective?

When I recovered our coach roof, I moved one of the horns underneath (in our case, in front of the generator), and sold the second one. This eliminated a bunch of holes and potential (re) leaks.

One horn, behind the front, facing slightly down - it is still very loud.

The horns are Hadleys - still worked fine after 20 years of full exposure.
