blinking butt

I was behind this truck and the red light kept blinking the moment the truck made a halt in the traffic jam. My eyes was so painful because of the blinking red light. *blink blink blink*

How could our lovely govt allow this kind of setting at the butt of the car / truck. It didn't help as we were caution there is a blink but our eyes hardly can open after a few blink... ended up we have higher chance to kiss the butt.... Sigh~
