The present disclosure relates generally to braking indicators. More particularly,
the present disclosure pertains to a brake light(s) system for a vehicle.
BACKGROUND
[002] Background description includes information that may be useful in understanding the
present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[003] Each year high-speed rear-impact crashes can be fatal to life, often leave debilitating
injuries and expensive medical bills. Over the years vehicle density especially two-wheelers and
four-wheelers have been increased enabling high-speed collision happening on highways
especially in low light, where vehicle owners tend to increase speed thereby colliding with each
other. Suddenly applied brakes by the leading vehicle doesn't even give an instant to follower
vehicle to apply a brake and the same impact keeps on, and hence several vehicles come under
this impact collisions. A large number of rear-end collisions took place each year causes crores
of damage, injuring many, and over thousands of deaths are caused. When traffic moves slowly
on highways the vehicle coming in speed from behind have very less time for sufficient braking
causing major collisions of a number of vehicles at same time. Statistics show large vehicles at
night time are a major cause of collisions, a slow movement of larger vehicles such as trucks
obstruct a clear view of road thus reducing reaction time of the vehicle to an unexpected
reduction in traffic speed. Some of unhealthy habits such as driving while tired, poor driving,
hectic schedule of individual, not focused, drinking while driving contribute to collision or
accident of the vehicles resulting in hundreds of deaths and injuries everyday.
[004] In prior techniques, speed sensors operatively coupled to a processor, said speed
sensor installed at every wheel regularly monitors and gives notification to a driver if speed is increased then a threshold or predefined speed. Merely giving notification to driver would require some time by the driver to think and respond to a situation that can lead to collision even after installation of speed sensors. The main disadvantage of disclosed invention is the individual

cost of speed sensor positioned at every wheel thereby not providing appropriate time for the
driver to react.
[005] In another technique, a system is disclosed with longitudinal control and collision
avoidance. The system discloses magnets and position sensors are positioned on roads of
highways, broadcasting vehicles relative position at every time, generating an audio alert for safe
driving and keeping distance between the leading car and the follower car. This proposed
technology is very complicated to be implemented and is not much financially viable at the
present time.
[006] There is, therefore, a need in the art to provide a vehicle brake alert system that
overcomes the above-mentioned and other limitations of the existing solutions and utilize
techniques, which are robust, accurate, fast, efficient, cost-effective and simple.
