The original model of the Enterprise was equipped with battery-operated lights, but even after the lights were deleted, a number of features from the lighted model persisted in the kit, including a removable main deflector assembly which had covered the battery compartment and served as an on-off switch for the lighted model. There were also indentations in the saucer section where the light bulbs were to be placed.
