Variable Message 12400 Nits LED Parking Sign IP65 Protection Class
Saving electricity Variable Message Sign Parking Guidance LED
display IP65 protection class
The parking guidance screen is displayed by counting the number of
vehicles (vehicle spaces) entering and exiting the parking access
control system. The status of the parking spaces is displayed in
real time, allowing the owner to select the optimal parking
position.

Product Introduction:
By embedding LEDs on some sections of ordinary traffic signs, the
effect of dynamically displaying road traffic conditions can be
achieved.
Shows the red, green, and yellow colors specified by the national
standard to indicate that the road is crowded, unimpeded, and slow.
In strict accordance with the 23828-2009 standard selection,
design, production and testing.
Compared with traditional traffic signs, it has the advantage of
traffic conditions;
More general LED variable information board, with energy-saving and
easy-to-understand advantages;
It has been widely used in Beijing and Shenzhen.
It is applied to indoor main roads in major cities at home and
abroad.
