Hi,
I think they were rescinded, but the boundary triangle markings were replaced by red lights in a triangle.
Please see quote from this link:
http://www.sci.fi/~fta/nightftr.htm
The illumination of the air-base was as follows:
- the obstacles outside of the base were marked by red lights,
- the borders of the base were marked by groups of red lamps, arranged with their tip pointing to the base,
- the landing direction was shown by accumulator lamps placed in a line at 50 m intervals,
- the arrangement of lamps in the landing direction was: three red lamps, followed by white lamps for the entire length of the landing area, then at the end 4 to 5 more red lamps. At a safe distance in from the border, a line of red lamps was located at the end of, and perpendicular (crosswise) to the main line of landing lights. On the left side of the first white lamp of the line, and about 20 m away, was another white lamp showing that the landings should be made on the right side of the line. If that lamp was located on the right side, the landings then had to be made on the left side of the line. The earliest point of touch down was to be made abeam the first white lamp and the latest, abeam the fourth white lamp. All taxiing was done on the opposite side of the line than the take offs and landings. The last 4 - 5 red lamps marked the end of the runway, and it was not permitted to taxi over the line of red lights that crossed the end.
- the take off controller`s position was located left of the first white lamp, and circled by red lights,
- located on the border of the airbase, on the left side of the light line, was a searchlight,
- the place for refueling, all obstacles, parked aircraft and aprons were marked by three red lamps,
- outside of the airbase, on the approach line, was a searclight transmitting the light code (changed from time to time) of the airbase,
- most of the airbases had a horizontal line of 10 to 15 lamps, located 1 to 10 km outside of the base, on both ends of the main runway (depending on terrain), pointing to the base. The objective was to create an artificial horizon to make the landings and take offs easier.
