P10 traffic light hassler is a period-10 oscillator found by David Buckingham on May 1, 1983,[1] consisting of eight blocks hassling four traffic light predecessors. The version in the infobox is the introvert, with all the blocks on the sides of the traffic light towards the center. The extrovert is also possible, with the blocks closer to the edge:

x = 17, y = 20, rule = B3/S23 5b2o3b2o$5b2o3b2o4$2o2b3o3b3o2b2o$2o13b2o$4bobo3bobo$5bo5bo3$5bo5bo$4bobo3bob o$2o13b2o$2o2b3o3b3o2b2o4$5b2o3b2o$5b2o3b2o! #C [[ THUMBSIZE 2 THEME 6 GRID GRIDMAJOR 0 SUPPRESS THUMBLAUNCH ]] #C [[ AUTOSTART THUMBSIZE 2 GPS 2 LOOP 10 ]]

Combinations of introverts and extroverts are also possible, and blocks can also be shared with other introverts or extroverts, or with another p10 oscillator.

On January 7, 2020, Jeremy Tan reduced the syntheses for both introvert and extrovert to 22 gliders.[2] Matti Ward and Ian07 further reduced the introvert synthesis to 18 gliders on January 9,[3] and Jeremy Tan reduced the extrovert to 20 gliders the next day.[4]
