Landing guidance droids, also referred to as signal droids, were droids that provided navigational assistance to starships during landings and takeoffs at various starports. These types of droids were utilized by the Star Tours travel company. One such landing guidance droid, LG3-18, was positioned on the moon of Nar Shaddaa, where it directed spacecraft to designated public landing areas.
The signal droid makes an appearance in one of the possible introductory sequences of the Star Tours: The Adventures Continue attraction; specifically, the scene that includes Darth Vader. In the ride, it has a mainly red color scheme, although the second iteration of the action figure modeled after the droid is instead blue. It would seem this droid takes inspiration from the INS-444 window installation droid.
