Air Horn Notes: From "L.H." - "I was reading through info on horns. I noticed that the add for Wolo 419 Bad Boy looks exactly like the Stebel compact air horn. Their price for the horn was high considering that I just bought a Stebel from California Sport touring for $38 and change including shipping. Wolo seems to charge for a few decals and cosmetic alterations. In addition the advertisement's instructions imply that you simply attach the wires from the original horn. That is misleading since a relay is needed and comes with the Stebel."
