Why use reflectors?
|
Sight is the
driver's most important sense. More than 90% of all messages to our brain
are visual when we are driving. |

When a car is traveling at a speed of 50 mph (80 km/h), it moves 73 feet per
second (22 meters per second). The average reaction time is one second
and the physical response takes another second. In this time the car has
already traveled 147 feet
(44 meters). A pedestrian without a reflector can on average be seen
at a distance of 100 feet (30 meters) with low beams. This
leaves the driver 1.3 seconds time to react and act. A pedestrian with
a Talmu reflector can already be seen at a distance of 500 feet (150
meters), which means that the driver in this case has almost seven (7)
seconds time to react and pass the pedestrian safely. There is a big
difference!

Talmu reflectors function so that the incoming light is broken three
times inside the reflector in its prisms and is then sent back to the
eyes of the driver. If the reflector is not water tight, which
means that there is humidity inside the reflector, the back reflection
will be lower or there will be none at all. This is why a reflector has
to be watertight. Hella Lighting Finland regularly controls the
reflection and water tightness of the reflectors. All reflective
values measured in production are automatically saved on a computer for
several years. In this way it is possible to follow up the
original reflective values of any lot even years later. |
