What is the blue light on 4g vehicle gps tracker?

Here, the red indicator represents the device power supply, the green indicator represents the device GPS signal, and the blue indicator represents the device GSM signal (device communication signal).

When the blue indicator light of the device is steady on, there is a call in or out; In normal cases, the GSM signal light of the locator blinks.

If the GSM light of the device is not on, it is very likely that the device does not receive the GSM signal or the SIM card is not installed inside. You are advised to check whether the device is loaded with a card.

The same goes for locator power lights and GPS signal lights.

When the power indicator and GPS indicator blink slowly, the device is positioned properly and the battery is sufficient. When the device indicator blinks quickly or turns off, it indicates that the device has low or no power, is searching for stars, or is hibernating.

Of course, each locator indicator is not the same, it is best to look at the instructions on the equipment manual, according to the instructions to determine the problem of the locator. If the manual has been lost, you can also contact the locator merchant directly to ask for specific instructions on the indicator light.
