(68607) USEING SENSORS AND LIGHTS INSIDE THE GOAL POSTS

The idea consists of using sensors on the goal posts to determine if the ball had entered the goal or not. and once the ball enters inside the goal the post must light on green. (a built in green light bulbs inside the goal posts).
this idea came to my mind when i saw some matches where the ball enters the goal and then gets out and the umpire doesnt see it because he is far away,and offcourse this goal can be seen in the repetition but the umpire had already said it is not a goal beacause he hadnt seen it first and if he changes his mind the is will make alot of confusion and stress in between the playesrs and the audiance.
and another reason is that sometimes we see how a player hits the ball toward the goal and we think it is a goal but really it isnt because it passes behind.(our eyes lies on us sometimes), so if we use the sensors and the light comes on then we will know dierectly if it is a goal or not.
using the sensor technic remindes me to the dress shops where you enter between 2 posts and when you hold a dress without paying the alarm will come on.
the ball should have a kind of magnetic bar or something similar to the ones inside the shops so that it can be detected by the sensors.
