Review: Great quality horns, nice and loud - Loud. That is what these are. I've installed these on my Hyundai Santa Fe as the stock horn on that car is nothing but embarrassing. I managed to replace them with these Hella horns without having to remove the bumper. It can be done by just removing the headlights. It is very tight though! Using some spade connectors, I created a wire to go from the horns to the existing wiring, no need to use the relay that comes with the horns in my case which helped make it even easier. I'm no mechanic by any stretch of the imagination. Really pleased with these although the new sound is different to what you might expect. All I cared for what the loudness and I got it.
Review: but all over they has a powerful sound and I am satisfied with it - They do sound a little pitch for my taste, but all over they has a powerful sound and I am satisfied with it.

## Questions & Answers

**Q: is the top side also chrome.?**
A: yes its chromed.

**Q: Has anyone tried these on the astra?**
A: Sorry, can't help with their suitability for fitting on an Astra, I bought these for a Ford Scorpio and have not yet fitted them. They are quite big so need a bit of space . I purchased Subaru wiring kit for them from the US to make the install a bit quicker and neater

**Q: are these a pair a pair or just one**
A: Sold as a pair with a relay.  There are more details in the product description.

**Q: I bought these to use on my motorbike but the connections look horribly exposed. Are these weatherproof?**
A: Hello Geoff, No they are not weatherproofed when manufactured. You will have to use plastic shrouded blade connectors which should offer some level of protection. If you are using the existing horn wiring circuit and connections on your motorbike. then these may already be fitted with shrouded connectors. I hope this helps

They do sound a little pitch for my taste, but all over they has a powerful sound and I am satisfied with it.

### ⭐⭐⭐⭐⭐ Worthwhile upgrade.
*by V***C on 17 March 2015*

Well made (in India), good quality, they produce a decent, loud tone, far superior to the original horn. They come with a Hella relay.
