I was reading about the audible flasher from chev of the 40's in this thread.

I purchased a 12volt audible flasher

Here is a test video in case anyone was interested in this flasher. ...TEST...

I will not be using this flasher since I installed the very bright L.E.D.s in the instrument cluster.
The Flasher very loud, the video doesn't really show how loud it is. Also it beeps....not clicks as you can hear
