Although the lights on your model's smokebox are mounted in what would otherwise be traditional class light location, on your model they are marker lights. Prior to the 1940s the Pennsy mounted marker lights on the pilot beam and class lights on the smokebox. Early in the 1940s the Pennsy stopped using class lights and moved the marker lights to the top of the smokebox as on your model. The markers in the new location did not have lenses on the side like the older style class lights. The lenses on your model's marker lights should be red and they would only be illuminated at night during reverse movements.
