Traffic Signal Lamp

Large vehicles may block the sight of drivers of small
vehicles in the back when waiting for traffic lights; as
a result, they may fail to tell the signals. The problem
can be solved by casting the signal in front of the larg
-e vehicles on the branch line so as to guide the drive
-r in the back.
