Features:

Name:Auto Voltage Detector

Voltage: 12V

Connected to 12V car battery, different voltage, signal lights have different performance:

1.0V-4.5V: The product can not start, please replace the battery in time.

2.4.5V-11.4V:

OK lamp flashes, other lamps do not light. The higher the voltage, the

faster the flashing frequency. When the lamp reaches 11.4V, the OK lamp

is always on.
