Solid Indication Design
OneSmartLightTM indications are designed as shown at the right. All three colors
meet MUTCD standards and are combined into one compact unit.
When one color extinguishes, the next color lights up in the same location but in
a different shape. Red is a solid square, yellow is a solid diamond and green is
a solid circle.
OneSmartLightTM indications are less than one third the weight and size of typical
three-section signal heads; the red light is 22% larger than existing indications.
