Bosch horn Chinese knock-off - PeachParts Mercedes-Benz Forum

I remember when I restored old Mercedes I used to refurbish the old Bosch horns, which sell for around $100 - $200 used. Today I went to the local parts store here in Guatemala and I found a nice knock-off for $5 brand new. I really could not resist, so I got myself one!

Looks like a forklift horn

430Hz? That's pretty high! I'm also curious how they sound!

My classic horns (Bosch "Europa" or "FSA2") are 300Hz and 375Hz for low and high tone, respectively.

Would there be anything wrong if I replace both horns for two 430Hz ones? Being loud is an asset down here, especially in the mountains and crowded places.

I miss the sound of the old MB horns my MB. Mine's got the American big car standard sounding one.

If you want them to be loud, wire them through a relay, so the horn pad will activate the relay and send power straight from the battery. This equates to louder horn response. By default, the stock disc horns in the W123 are not routed through a relay.

Using 430Hz on both might sound odd, the key to dual tone horns is the blend of both. What is the other frequency available?

The stock W123 horns are 400Hz and 335Hz, for comparison. The higher frequency is great for in-town or city driving, while the lower frequency is great for highway/open road driving.
