The system is very simple and very versatile. The fact that you can spread your arms out to form a directional arrow or leave them in to form a directional stick makes traffic control quick and safe. Using magnets on the base I was able to change the lighting scheme you have three of, attach it to the side of my truck and handle the accident I was responding to. Multiple LEDs are very bright, which is what you need during the day and precisely at night. I have no doubt that this will take a very long time. Another great benefit is that the system runs on AA batteries, making it easy to keep running. I will order more. One note I would like to make about the magnets, they are not strong enough to hold when the vehicle is in motion. 3 stars for the weather protection because I haven't used it in the weather to determine if it's there or not.
