The LED Lights Barrier design aims to improve the road safety when you encounter problems on the road. When your car breaks down, you need to set up an emergency triangle sign or a barrier to alert oncoming traffic. However, sometimes, fog and heavy rain can cause poor visibility on the road. Using this newly designed lights barrier, other vehicles will notice you even under poor visibility conditions. My sister had an Audi A4 and one of the coolest things about the car was when you opened up the center console in the back there was a first aid kit as well as a barrier very similar in shape to the LED Lights, just without the light. I think this is such a cool invention and a great product design in terms of safety and practicality!
