How does a smart turn signal work?
Intelliturn has engineered a smart turn signal system for cars [13]. Using sensors that compute how much the car has turned and then applying machine learning , the smart turn signal system can detect when the car is switching lanes or turning. Through this detection, this smart system can notify drivers when they forget to use a turn signal from the previous left turn as well as apply the self-canceling feature for all functionalities. The technology is still in the early stages but this can be a very promising feature that will alert drivers to use car signals and prevent any premature shutting off of signals by drivers.

Why do brake lights have red lights?
The proponents of red color argue for the cost effectiveness and simplicity of the design to use the same color for displaying the different information. In some of the older designs, instead of having a separate turn signal lamp, the brake red lamp is used for all the functions; it’s a steady dim for tail, steady bright for brake, and flashing bright for the turn signals. This is due to the requirement of each lit lens area to be at a minimum 50 cm2 [5]. In the 1950s, SAE lighting committee calculated the most effective luminous lens area. Among other factors, it was to ensure that the bulb when overheated would not crack the lens. By placing this parameter that required the 50 cm2 area to be all lit, it forced a certain distance from the bulb to the lens so that the 1950s non-heatproof plastic lens wouldn’t crack [5]. This meant that having multiple lenses for different functions could make the rear look clustered and not appealing. Thus, the brake light was used to communicate all functions.
