yeah, has to be a continuous tone, cant be a squeezie bulb one unless its pre1972 and cant be louder than 112 dB (though no MOT station has a dB meter)sorry to jump thread is a standard horn a requirement for mot or can i use my rally horn
no mate, doesnt need another relay, the existing one will be fine, just wop the new horn on and away you gook back to me...lol
ok so its just a case of bolting it on...does it use an extra relay or anything?
