LED Arrow Board are technically arrows that light up on an LED sign, but may confuse them with traffic message boards. Traffic message boards display messages such as “paving from 8:00PM to 4:00AM” or something similar. They are used to inform traffic about changing road conditions.
China LED Arrow Board can either be mounted to the back of trucks or can stand alone on the road. The only thing ‘true’ arrow boards warn about is to get in the other lane. They are usually behind a salt truck or snow plow let you know that you should switch lanes.
