This is a red-domed, 4-lamp rotating Emergency Power Lamp by:
Federal Signal Corporation
Pat. No. 3,271,735
This patent was issued on September 6, 1966, Warning Device For Emergency Vehicles, to Earl W. Gosswiller, assigned to Federal Sign & Signal Corporation, Blue Island, Ill., a corporation of New York.
Filed on June 29, 1964, serial no. 378,754
In photo #4, there are 2 of these on the top of a 1970's Cadillac Ambulance.
I think this will be my new "Halloween Porch Light".
Not sure what category to put this in.
Thanks for looking,
