What image is on the front of the billboard? From the pictures I am not sure what you purchased. The 577 has the lights but not the solenoid. The 762 Two In One billboard has the solenoid but is not illuminated.
The 762 comes with a two button control attached to the billboard with a 3 conductor cable. Two wires from the button attach to the 15V and Base Post terminals on the transformer. One button completes a circuit from 15V to base post for just the motor. The other button completes the circuit for both the motor and the solenoid. A fourth wire would be required to illuminate the billboard.
The lights sure look factory.
