I have always said that the T2 horn sounds like it's pleading and wheezing at the person, where as I like one that says in no uncertain ways.. "Move that pile of $(&^ out the way and "$£$ off.
So, I changed my original T2 ones for some smart red snail shell Hella ones, that promised the earth, and delivered dirt. They were marginally better than the T2 ones, but definitely not as promised. Luckily, I then drowned them doing 4x4 Response work in the flooding. The shape means water can get in, and lay on the diaphragm, rusting it away, even when mounted facing down.
So, as they got more and more feeble, I took the opportunity to take the two off of the old Volvo before it went, as in the old days of the 240, Volvo fitted horns for moving Moose, and they are great. I fitted them, which are a lot better, and because of the design, less likely to hold the wet.
They were good, but when the opportunity for one of those self contained airhorns came up, at a great price, I could not resist. So I now have that fitted, as well as the Volvo Moose horns.
I don't use the horn very often, most times, it's easier to take avoiding action, rather then waste time pressing the middle of the steering wheel, so apart from a couple of quick tests, it's hardly used.
I actually used it properly for the first time yesterday when in slow moving/stationary traffic on the M25, some old moron in an Audi started to roll back into me. Luckily, I had a good gap, but as his speed started to build up, I got worried. I hit the horn, which was in fact a great idea, as everyone looked over, and I would have had plenty of witnesses that I was in fact stationary. Luckily he got the message, although he acted like he had done nothing wrong, and it was me who was out of order.
Anyway, as we pulled away, Suz tuned to me, and said.. Wow, now that's what I call horns...
Funniest bit was, he then cut a lorry up to get into the next lane, and got hooted at again. How that was what I call a set of horns...:doh
