I added an air horn because of too many close calls, and bike horns just don't cut it sometimes. Some might argue it is a silly addition, but I feel better having it.
Compressor mounted to the right down tube...I think that was the original horn location (it's been so long).

Brackets were from snatched from some truck mirror parts. Flat stock was what came in another electric horn. The brackets fit nicely around the frame.

It all fits in there. I will clean up the installation a bit by reversaing the bolts and trimming the relay screw down flush. It must have been cold out when I did this BITD.
