Cat eye on road was originally invented in the 1930s by Workshiremen Percy Shaw, and is now used
as a road safety measure around the world. Cat eyes on the road are about to be a thing of the past,
and British government ministers will amend legislation and replace them with new LED solar road studs.
The new LED road stud can be seen as far as 1000 yards, 10 times the current recognized cat eye
model. The new lamp can be recharged for 4 hours, can work up to 10 days, and has the same service
life as the traditional cat eye. These new led road studs are also affectionately called solar/led cat eyes.
The addition of embedded LEDs to each cat eyes road stud provides these reflectors with significant advantages over traditional cat eyes. Since the reaction time is primarily based on vision, the LED cat eyes allows the driver to reach a reaction time of 30 seconds as opposed to 3.2 reaction times from conventional cat eyes. Drives with ten times visibility can reduce accident rates by up to 70%.
The new design LED road studs has been used in some traffic accident blackspots in the UK, but still
includes reflective bars-because traffic regulations currently require the use of "reflective road stud".
It has been said that once these rules are changed, technology can move forward and provide new
alternatives. Current cat eyes rely on vehicle front lights to reflect them, but the new cat eyes on road
will be fitted with LED, inside them, which means they will shine automatically even if they don't rely
on the headlights of the vehicle.
At present, this kind of cat eyes road studs is increasingly introduced by parliaments related to road
safety. Some people said: "We hope that they will become norms, they have clear road safety benefits and other benefits for drivers." When using LED cat eyes, the pressure of driving is much lower, because the driver can see farther ahead. They have also been shown to improve road discipline.
