From: Operation High Time. (http://www.simegen.com/sgfandom/rimonslibrary/oht.html) A standard marker that was used to supplement light by creating an interference pattern that Simes could sense. Mairis Farris used these so they could be located when he and the Fieldmans were being held captive.
(Source: Index card file. Operation High Time http://www.simegen.com/sgfandom/rimonslibrary/oht.html) Reeves projectors mounted on huge poles at abandoned copter field. Markers used to supplement lights, creating an "interference pattern" any sime can sense --- take hours to warm up.
