[FC] Hazard flasher

[Tom St.Amand]

Great work everybody on all that backup light info. I have another question someone might have an answer for. I bought a 64 parts van and it has a 1/2 round red flasher light ( I think  it looks just like the one my 65 Monza had. ) mounted into the cigarette lighter hole. My 65's was mounted on a bracket under the dash.  My question is was that a dealer installed option, although I doubt that was the preferred location.
Thanks for your help,
Tom St. Amand
