TRM Taxiway Reflective Markers are used to mark the edges of taxiways and ramps at airports and heliports. They are particularly useful for taxiways with centerline lights that do not have edge lights. For all airports, TRM markers provide daytime delineation of the operational areas. Therefore, they are often used to supplement edge lighting systems. All TRM markers feature a white tubular post and a 14˝ reflective material height.
