Lane Control Signal Light

We are offering lane control signal light, ohls.
The over head lane control sign (ohls) is located on the leading edge of the canopy covering the toll lanes above the center of the lane. The purpose of the ohls is to indicate to the user whether the toll lane is open for the processing of vehicle or closed. Red full round or red cross is used to signal that the lane is closed, whilst a green full round or arrow is used to indicate that the lane is open to traffic.signs are sufficiently bright and directed to indicate to a motorist, approaching the toll plaza, at a distance of 600 m on a bright cloud free day that the lane is available for use.
