OneSmartLightTM indications are designed as shown at the right. All three colors meet MUTCD standards and are combined into one compact unit.
Arrow signal indicators are outlined with the same shapes used in the solid indicators. When one arrow and outline shape extinguishes, the next colored arrow and outline shape light up in the same location.
OneSmartLightTM indications are less than one third the weight and size of typical three-section signal heads. Typical left turn signals are installed at the end of the mast arm which produces stress on the bolts; OneSmartLightTM reduces the stress due to its lighter weight and smaller size.
