Hazard Warning & Turn Signal Indication Technologies and Acquisition in Automotive Sector

This work aims to review the hazard warning & turn signal indication technologies used in automotive sector, as a whole, heretofore and to conjecture a suitable circuit-based technology acceptable to driver and implementing automotive industry, ultimately. An issue has been faced by most drivers that turn signal cannot be indicated, once the hazard warning signal is on. This may lead to accident. It happens due to the wrong assumption of driver that turn signal is on, while taking a turn, but turn signal cannot be indicated, in effect, as the hazard warning signal is being indicated and it overrides the turn signal manifestation. However, technologies have been developed into which the turn signal indicated, if activated by driver, overrides the hazard warning signal indication. Still, these technologies are not into practice, due to either non-acceptability of those technologies in automotive industry or implementation issues, perhaps. Therefore, there exists scope to develop more technologies of same kind which may lead to same results, but in more effective manner which will be automotive industry friendly and easy to implement.
