Key Products

Whether for traffic lights or message panels, the use of LED traffic signals is increasingly widespread in both permanent and portable, battery-operated systems with photo-voltaic panels. In addition to the basic display function – with ambient light sensors to adjust for brightness – traffic signals can be connected to a control center for re-programming and monitoring purposes and might have GPS tracking to enable effective monitoring and maintenance.
