Features: The active light-emitting part adopts high-brightness LED light source, uniform illumination, soft light, no glaring, good stability. The passive light-emitting part adopts ultra-high-strength reflective film, which can also reflect the car light well in the case of power failure. Strong warning effect, the visible distance can reach more than 500 meters. Energy saving and environmentally friendly, low power consumption, long life, double-sided illumination induction standard power is only 0.45W. Equipped with voltage regulator and anti-interference chip, safe and practical, low failure rate, easy to install. Exquisite appearance, the main body is made of flame-retardant PC/ABS plastic; the transparent body is made of transparent polycarbonate, which has good light transmittance; the sealant is made of modified silicone resin. It is mainly installed on the curbs of highways, tunnels, road shoulders, roundabouts, safety islands, and the entrance or exit of underground parking lots or on the walls of tunnels and on the side wall of roads.
