The green color gives you permission to drive ahead or cross. Red and green colors are usually the ones that last for a longer period of time, compared to yellow. In some cases, you might have to stay at the Novelty Lighting for five minutes or more when the red light is shining. This is usual when construction work is done around the road. Some countries have the practice to turn off the red and green in the night until the morning, and leave everything to the yellow light and the traffic signs. This is effective in towns and cities with smaller populations and less traffic.

Some traffic wall lights are improved via sound effects. This is done to ensure the safety of pedestrians who have vision problems or are blind. The practice is that when the color is red, a sound will beep slowly, indicating that you cannot cross. If the light becomes green, a continuous sound indicates that it is safe to cross. These pedestrian crossing panels are usually disabled at night to ensure that the nearby residents are not disturbed by the annoying sounds.It is no surprise then that traffic lights became very popular and have been used for over 100 years now. They prevent many traffic accidents and ensure the safety of the people. Something that hasn't changed in such a long time is surely here to stay on and on.
