One indicates that the brake pedals are pressed, therefore brakes are on. The other indicates that the park brake is set. In the case of a Boeing that means pressing the pedals and pulling the park lever on.
In Airbus world the park brakes are set by a rotary switch.
Re: 737, I'm guessing that due to the design, with the nose leg being so short any lights would be so low down as to be next to useless.
The lights are there on other types as an added indication to the tug driver I assume as the headset man is usually stood off to one side out of sight of the lights.
