This is a rather strange question - did fire trucks ( especially in the '50's ) ever have roof marker lights ? I don't remember seeing any but I never really took the time to look . I'm thinking of swapping cabs on my fire truck with one of the two better cabs that I have but they have marker lights . It would be easier to fill those ( the marker lights ) holes than replace the floor and cab corners on the existing cab . But if if I could find evidence that fire tucks had marker lights ( sometimes) that would make it even less metal work for me . Thanks Weird ED H
