Car part to honk (4)

I believe the answer is:

horn

(Other definitions for horn that I've seen before include "Musical instrument; Chile Cape" , "Bony outgrowth on an animal" , "Instrument - rhino's feature" , "Instrument - rhino's appendage" , "familiar to the matador?" .)

I've seen this clue in the Newsday.
