I have a set of Horns out of a 1990 Cadillac Fleetwood Brougham installed on my truck. Yesterday, I was on my way back from the gas station when I spotted a friend of mine, I sounded my Cadillac horns which are wired up as my stock horns and he waved back. I get a phone call from him and he said that there were these two girls in front of him who Jumped and screamed! lol. He said ‘was that your train horn?’ I said “No, it was my regular horn lol”. He told me that he said to the girls that it was just my regular horn and not my train horn.
Here is a little sample of what an old school Cadillac Horn sounds like, Please note, there are a total of 4 Electric 12 volt horns all together D, F, A, C. They produce this. http://www.youtube.com/watch?v=1pSQQ-uSoTI
They are Brand New Replacement type horns, but there is No C Note. If U want I can go up to the Junk yard this Friday and see if I can find a set and clean them up and ship them to you. Of course I will test them out first and make sure all four horns are working.
