While watching the Discovery Channel today, I was reminded of a programme which they had aired a few years back. The Programme had a Technical Expert team from the Mercedes-Benz discussing about the advantages of using flashing Rear lights in their new cars. They demonstrated the positive effects of using flashing rear lights in the cars. According to their research and studies, the driver reaction time was reduced by 33% when flashing rear lights were used in sudden braking conditions.
The working of flashing rear lights can be seen in the following video. The first half of the video simulates sudden (emergency) braking conditions whereas the later part simulates the normal braking conditions. As observed, the rear lights flash only when sudden braking is involved.
How Flashing Brake lights protect the passengers
- Brake Lights flash rapidly during emergency braking to alert other drivers
- Blinking LEDs get the attention of distracted drivers
- Reaction time of following drivers is shortened by 1/3
- Other drivers are alerted of emergency braking situations, so they brake harder and earlier
The following video shows how the flashing tail lamps effect the braking of the car.
Impact of Rear End Collision Avoidance Systems
- Flashing LED brake lights can shorten driver reaction time by 0.2 seconds, from 0.6 to 0.4 seconds
- At 70 mph, 0.2 seconds equates to 20 extra feet of braking distance
- Rear end collision avoidance system can prevent 80.7% of rear end collisions
- These systems can reduce the severity of accidents that still occur by 96.5%
The cost of setting up a Flashing Brake lights setup in a car is less than INR 500 (around US$ 10). If the Vehicle companies include the same in the cars manufactured by them, the cost per car will be even lesser. Hence, it is possible to avoid almost 80% rear end collisions by installing a setup which costs less than INR 500.
I think it would be great to see something like this in Indian cars. What do you think?
