Front vs Rear LED Turn Signals

LED turn signals are becoming a popular trend among drivers, not only because they are more durable and last longer, but because they save a lot of electrical power. Turn signals are safety devices that warn other drivers of the next direction for the car. When a turn signal is lit on one side of the car, it immediately signals the other drivers that you plan to move to another lane or to turn to another direction. LED turn signals can be installed both at the front and rear of the vehicle. To determine the difference between front and rear turn signals, read on.

Purpose of Installing LED Turn Signals

Front and rear turn signals have the same purpose, and that is to inform driver and pedestrians quickly of your plan to shift direction. The only difference between the front and the rear turn signals is the direction they are flashing. Front turn signals inform drivers and pedestrians at the front of the car of any change in direction. The rear turn signals do the same, but for the drivers at the back of the car. It is important to turn on the directional signals in order to avoid crashes and accidents. Although having a faulty turn signal is not the major cause of car accidents, it does contribute to the frequency of accidents. Therefore, it is the driver’s responsibility to check if both the rear and front turn signals are working perfectly or not.


There has been a constant debate on which color is more effective for front and rear turn signals. The two colors that have been used for decades are red and amber, but white is sometimes used for the front turn signals. Color is an important aspect of automotive lighting because it warns other motorists of the driver’s plan of action. Since white is usually used for lighting the road, then it is not a good thing to have other light fixtures have the same color. Therefore, turn signals are required by law to be either amber or red.

In recent studies, amber was found to be the most effective color for turn signal lights. Although some people still dispute the findings, it is worth taking note that that amber has been widely used as a turn signal color, especially for rear turn signals. Therefore, when choosing a color for the turn signal, make sure to follow the correct color codes. Amber, red and white can be used for the front lights. Only amber and red should be used for the rear turn signals.

The Bottom Line

There is not really a huge difference between the two turn signal lights except their location. However, it is important to take note that these two should work together as a unit. Therefore, they should both be working at the same time to enhance driving security and avoid accidents. Replace damaged LED turn signals as often as needed and make sure to check on them regularly.
