What light signals or visual markings indicate that turns should be made to the right at class G airports? FAR 91.126 states:

§91.126 Operating on or in the vicinity of an airport in Class G airspace.
(a) General. Unless otherwise authorized or required, each person operating an aircraft on or in the vicinity of an airport in a Class G airspace area must comply with the requirements of this section.

  airports have L-shaped traffic pattern indicators displayed with a
  segmented circle adjacent to the runway. The short member of the L
  shows the direction in which the traffic pattern turns are made when
  using the runway parallel to the long member. The pilot should check
  the indicators from a distance or altitude well away from any other
  airplanes that may be flying in the traffic pattern.




Here's what it looks like at Huntsville Executive (KMDQ), which has a right-hand pattern for runway 36:
