No girl's Hornet in 1959. Correct light as shown in your B&W catalog page. The '59 and up bikes when they used lights on the fender tended to use lights with wings or angles to mimic the lines of autos of the day or suggest jet flight.
The front loaders were typically prewar, top loaders post war, and look quite similar to each other. You could also go with a Rocket Ray, which although not technically correct could have been a light a kid could have upgraded to.
