What is a turn signal called?

In Malaysia, car turn signals are commonly referred to as "direction lights" or "turn signal lights", with the English term being "turn signal". This is an important safety device on vehicles used to indicate driving intentions to other road users, such as when turning, changing lanes, or making a U-turn. The operation of turn signals follows the "up-right, down-left" principle—pushing the control lever up activates the right turn signal, while pushing it down activates the left turn signal. According to traffic regulations, drivers should activate turn signals at least 3 seconds before turning or changing lanes to ensure adequate reaction time for surrounding vehicles. Modern vehicles predominantly use LED technology for turn signals, offering advantages like fast response time and long lifespan. Proper use of turn signals is not only a legal requirement but also fundamental to safe driving practices, effectively reducing traffic accidents caused by miscommunication.
