The arrow-shaped prismatic reflective film is mainly used for nighttime reflective warning and direction guidance, applicable to three core scenarios: in traffic roads, it can be attached to guardrails or warning signs with arrows aligned to the driving direction to ensure visibility from 100-200 meters away; for vehicle identification, it can be affixed to prominent positions on the body of trucks, engineering vehicles and other vehicles to indicate driving or emergency directions; for site guidance, it can be stuck on the ground or walls of garages and parks to point to key locations such as exits and fire passages. When in use, it should be applied to flat and dry surfaces, pressed firmly to avoid air bubbles, and high-intensity or micro-prismatic grade products are preferred. Faded or worn films should be inspected and replaced regularly.
