Cool projects! I've experienced hearing what sounded like a semi pass me, only to see that it was a small pickup.

Ha! But you heard him, right?

When I'm riding or driving a sports car, I'm all about conspicuity - both visual and aural. Can't be too careful!!

Jon, KB. & DIYer, Thanks for the welcome. I have this Galaxy Tab4 device & I will figure out how to post some pictures out of the gallery, eventually, Ha! I feel old somehow

As to dimensions, the longest horn (C#) is 21.25" from the back of the 3" dia. pvc reducer "diaphragm/nozzle chamber" to the 4" dia. funnel flare "outlet". The shortest (A) is 15.375" long.
All 3 horns are attached to an angle aluminum bracket, w/ U shaped handle & 0.5" id ball valve to control the airflow. The 5ft. air supply hose goes from a galvanized pipe manifold on an 11gal. Craftsman spare air tank (135psi max.) The tank still has the Safety Relief valve & original tire chuck & hose. I have no compressor yet (too expensive), but get free, dehumidified shop air from work anytime I want.
