Choosing 400mm and 500mm LED Traffic Lights for Highway Approaches
400mm and 500mm LED traffic lights are used where a large signal indication is needed for approach visibility. This range includes ball, arrow, pedestrian, bicycle, lane-control, and countdown configurations. The final configuration should be selected around the road layout, controller, voltage, and mounting design.

- Choose 400mm or 500mm optics according to the project design and local standard.
- Confirm the indication type: ball, arrow, pedestrian, bicycle, or lane control.
- Provide voltage, controller interface, mounting method, and required housing material.
