  • Ultra bright LEDs improve the awareness and visibility of the school bus by providing uniform illumination visible from 1,000+ feet, visible up to a 180° angle, and readable from 300+ feet.
  • Sign panel is sealed, prevents water and dust intrusion to an IP67 rating and rated to a temperature of -40°F to +185°F so the sign will stay illuminated in the harshest climates.
  • Easy installation and maintenance - Stop Arm uses only four fastening points to mount to a school bus which are sealed to significantly reduce moisture from entering the bus. The universal drive unit mount is designed to easily replace existing stop arms or can be installed on new buses.
  • Long product life with over 50,000 hrs of operation. Illumination only.
  • Durable lens material is impact and scratch resistant.
  • High torque motor provides reliable deployment in high wind conditions and eliminates faulty deployment.
  • Smart Obstruction Detection technology senses when excessive force is detected and stops operation to reduce the risk of premature motor failure and structural damage.
  • UV resistant link and lens to provide maximum resistance to environmental fading
  • Independently powered strobe lights/flashers - loss of one strobe light/flasher does not result in loss of all strobe lights/flashers
