Product Details
Variable speed limit sign(vsls) is an effective way to attract driver's attention, especially while driving on expressway or on road nearby school zones, hospital or residential neighborhoods. We offer a full range of VSLS different sized roundels to increase the speed limit awareness.
● It works for 7x24hrs
● Lower energy consumption
● Wide pixel pitch range
● High compatibility of communication protocol, including NTCIP, UTMC, Profibus and modebus communication
