*CLUTTER*
Clutter refers to the excessive groupings of lights. Groupings of lights can potentially cause accidents to occur. For example, clutter is particularly obvious on roads where the street lights are badly designed or where brightly lit advertising surrounds the roadways. Depending on the motive of the person or organization who installed the lights, their placement and design may even be intended to distract drivers which contribute to accidents.
Figure 5 Clutter of lights reflected on glassClutter is also a hazard in the aviation environment, if aviation safety lighting must compete for pilot attention with non-relevant lighting. For instance, runway lighting may be confused with an array of suburban commercial lighting and aircraft collision avoidance lights may be confused with ground lights.
