When lighted lamps are not required, what must be used as indicators instead of flares, lights, or reflectors?

In scenarios where lighted lamps are not mandated, the use of two red flags is established as an alternative method for signaling or indicating an issue. This choice aligns with safety protocols that ensure visibility and communication in potentially hazardous situations. Red flags serve as a standardized visual warning that can effectively capture attention, especially in environments where visibility may be compromised due to poor lighting or other conditions.

Using flags as indicators is particularly advantageous because they are relatively easy to deploy, lightweight, and can be easily seen from a distance. The color red universally signifies a warning or alert, making it an appropriate choice for drawing attention to specific areas or situations without the requirement for electronic or lighted equipment.

Other options like white flags, red lights, or yellow cones do not fulfill the same role as effectively in contexts where non-lighted indicators are specified. White flags may signify surrender or neutrality, which is not suitable for warning purposes, while red lights are reliant on electrical components and are not an option when lighted signals are not allowed. Yellow cones might provide some level of indication but do not carry the same urgency or warning connotation as red flags.
