Fluorescent yellow-green signs

Type A, retroreflective signs: Surface uses the fluorescent yellow-green reflective film material, adhered to an aluminum alloy baseplate. It relies on vehicle headlights to produce reflected light, with a maximum visibility distance on clear nights (with higher-grade reflective film materials) of up to 395 ft.

Type B, panel display active illuminated signs: Surface uses the fluorescent yellow-green reflective film material (transmittance > 25%), with an LED light source panel placed inside the box structure. Borders and connections are made of aluminum alloy profiles or stainless steel. They do not require vehicle headlights, with a clear nighttime visibility distance of > 660 ft. They can also be clearly visible when visibility is lower than 660 ft due to rain, fog, etc.
