The TOPTREE TPBL20W is an innovative LED line light specifically designed for industrial vehicles, particularly forklifts. It effectively prevents accidents by projecting highly visible lines onto the ground, delineating safe working areas and potential hazard zones for operators and pedestrians. With its exceptional durability and wide temperature adaptability, this line light is an ideal solution for upgrading forklift safety in extreme cold working environments such as cold storage and freezers.
- Stable performance even at extreme -40°C
- Improves safety visibility for forklift operators and pedestrians
- Prevents accidents caused by slippery floors and poor visibility in low temperatures
