Hello George, It does come with what Ritchie calls "Internal Marine Night Lighting"

The manual states as followed - Remove the base by “squeezing†the buttons on the side of the housing while carefully pulling on the base. Mount the base as instructed (see Installation above). Re-install the compass and begin compensation (see Compensation instructions below). Note: the mounting holes for this model are slotted, so by centering the mounting screws within the slots you can install all screws and make your alignment corrections later. Mounting pads are provided if you do not wish to drill any holes. Remove the mounting pads from their backing and stick them over the mounting slots. Because alignment is difficult to veriify at this time we suggest temporarily securing the base (masking tape works well) until after compensation. After alignment has been verified, make a small pencil mark at the front and back of the compass and deck. Remove the remaining backing from the pads and secure the base to the deck using the pencil marks as a reference.
