Twin horns
One of my horns has packed up and the other, well, its useless.
I am sure I have a pair of horns in a box somewhere but if not could anyone tell be what I should be looking for when buying twin horns? I think one is high tone and one low tone but apart from that and being 12v I know nothing. Cars with one horn, is it the high tone, low tone or are different? thanks macafee2 |

As I understand it, single horn models have the higher note one. That's why they sound a bit too silly for a large car. The best route I found, was to get a pair of matched twin horns from eBay. The 'snail shell' type will be a direct swap. Their notes only differ by 10-20Hz which gives them a more suitable tone when sounding together. Virtually any 12v twin set will do. Wire them in parallel.
Example: https://www.ebay.co.uk/itm/263016185...kAAOSwKKxg9U99 These are cheap and cheerful, but prone to internal rusting over a few years. I opened them up and gave the insides a good spray of WD40. Otherwise, buy a more expensive set. TC |

The OEM horns for the twin horns are Hella, and I think 400Hz and 500Hz frequencies. The single horn cars it was only low tone that was fitted.
https://www.ebay.co.uk/itm/265185635...AAAOSwPUNguNpS I would stick with OEM horns, rather than go for some cheap horns from China. |

Been into the garage and have found a pair of horns from a Rover 75. Just have to check they work.

I have the Fiamm ones fitted, my original horn was the little gentle one from the factory, these are very loud, I've had them fitted for a couple of years and can recommend them.

It does take penny pinching to the limit to remove one of the horns to leave a car like a 75 sounding more akin to Noddy's car. I think the OEM horns are plenty loud and melodious enough. |
