What color is the turn signal light? It's easy to think but 90% of people answer wrong

Use motorbikes and cars everyday but do you know what the turn signal light of the vehicle (navigation light) is in color? If the answer is orange or yellow, you are wrong. In fact, the colors of popular used lamps are in amber colors . And the reason people choose this lamp color has a reason.

Navigation lights are patented for the first time in 1938, and are almost immediately applied by most car manufacturers around the world. By 2013, vehicles on the road in most countries were required to have turn signals.

The turn signal light was first patented in 1938.

Turn signal lights must also comply with technical standards such as minimum and maximum intensity, viewing angle as well as lighting surface area must be visible from all angles, can be observed in environment with strong light without making the observer blinding.

Since the 1960s, most front turn indicators have been designed to emit white light, while the rear lights have red light. Since the beginning of 1963, the US auto industry decided to use amber color to design the front lights because the recognized amber light could be quickly discovered more than red. According to American research, the driver of the rear vehicle is more accurate and responsive to the amber turn signal in the vehicle ahead.

Recognized amber light can be quickly discovered than red.

Currently, most of the countries in the world (except Switzerland and New Zealand) stipulate the front and rear turn signal lights must produce amber light.

According to the regulations in Vietnam, the turn signal lights of motorcycles and motorcycles must have amber or red light.

In 2008, the US National Traffic Safety Administration (NHTSA) announced the results of the study showing that vehicles equipped with amber color turnarounds reduce the number of collisions by up to 28%. In 2009, NHTSA identified an amber turn signal light that provided a significant overall benefit when compared to a red turn signal.
