1. The luminous unit of signal light, housing, and shielding surface are smooth, without cracking, no silver wire, no obvious deformation and burr, and the color of the housing is obviously different from the color of the light signal; , Provide standard power interface

2. The signal lamp with light distribution design mask, the light emitting surface of the light emitting unit is uniform and the pattern outline is clear. Unpatterned signal lights using light-emitting diode (LED) light sources and transparent face masks.

3. Solar yellow flashing warning light is a traffic facility developed with advanced LED luminaires. It uses solar panels to supply power without external power supply. It is an ideal traffic warning sign for traffic crossings without external power supply. Low, long life, low operating cost, known as a green product. This product is composed of ultra-bright LED array, single-chip micro controller, solar panel, maintenance-free battery, bracket, etc. It is suitable for vehicles that need to be set to guide and warn Exercise section.

4. The solar energy resources are very rich. The use of solar energy resources to develop transportation facilities is not only environmentally friendly, energy-saving, but also convenient.
