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. |
