Air horns

Recommended Posts

I bought an airhorn from Halfrauds, it was straight forward to fit... It took me about 30 mins to work out how to wire in the relay, but that's with no real prior knowledge other than physics A level lol!!!!!

 

It sounds well better than the stocks, although.... A bit tram like :)

 

I moved the battery a few inches left towards the engine, this freed up enough room to fit the compressor by the water washer intake. There was even an attachment bolt already there on my car, not sure if this was an old alarm install or generic!

Re: the air horns, fitted a set to mine behind mesh front grill. I made a bracket & mounted both horns & compressor all in the same location (used the OE mounting bolt for the low tone OE horn). Also used the original feed to same horn as OE is fused correctly for both the originals & the airs. Two tones are not illegal, as any vehicle with two horns (i.e. Jags, most fords, GM etc. etc. etc. now have two horns!). As for MOT's, I've fitted them to every car I've had since Noah landed & no-one's said squat yet!!! I do have "Dukes" on my 4 Runner, however they are on a separate switch. Hope that helps.:flame Dev

i think we getting a bit confused here, there is a differance between 2-tone horn and 2 horns with same tone?

2-tone is normally related to two different sounds like want the police/fire and ambulance make which is only legal on emergency vehicles. you can fit 2 or even 20 as long as the tone of the horns sound the same. and is continious. then there is no problem.

Whats all this fuss over legality..... I wouldn't loose any sleep over it, just cross your fingers if you get pulled cos' your horn just happens to play the intro to the god father, that they don't do an emissions check as well.... :)

I'm not confused at all. Two tones - means two different notes - standard vehicle or AM two tones play both notes (tones) simultaniously (coulda' spelt that one wrong!). Whereas emergency services have two tones played alternatively - same product, just plumbed differently for Em. Serv. (plumbed like Dixie or La Cucaracha):flame Dev Only horny little devil I could find!
