S210 Horn location

[welland99]

My car must have at least two horns. I have found one in front of the radiator, but there must be another somewhere that I can't see. I've looked all around the engine bay, but still can't spot it.

Anybody got any ideas?

The other is behind the bumper below the offside lamps.

Access is from below by removing the wheel liner.
