1960 S&S Cadillac Lights Question

[Paul Steinberg]

In the picture below, what did S&S use for the front mounted roof lights. I have seen a lot of taillamps used for emergency warning lights, however, these have me baffled.
Also, second question... What does the second script on the lower portion of the front fender say. I can see the first script is a S & S.
Thanks
Paul
