This is the latest digital light bar ,we just made some samples for our client it's in DC24VCC and 8Pixel with 

48 LEDs only , in the begining of each bar we put a component for safe ESD protection DATA in wires and 

there is a clear lens on top of each LED to An-UV and acid rain connectors also important, we used our regular 

and reliable one.
This bar can not be : No slot joint which means not a good solution to make a outdoor screen as you will see 

there is a gap and the pitch bigger than other LED 20.83mm (1000mm/48 LED) the PCB is 990mm and LED 

Bar size is 1000mm,but the connector cable output from end of side(digial led line).
