This device is usually used in roads, bridges, tunnels or other traffic facilities to ensure that vehicles and pedestrians can clearly see the signs, thereby improving traffic safety.

[0003] Signs are usually installed on the road for display. At night, vision is easily obstructed, resulting in the signs on the poles not being clearly seen. Therefore, fill lights are installed for lighting display. However, common fill lights are fixed in one position and do not have the effect of position adjustment. In addition, the base of the fill light is fixed by bolts. After multiple disassembly and assembly, it is easy to cause thread slippage, or long-term water stains may make it difficult to continue disassembly and assembly, thus bringing certain inconveniences. Utility Model Content
