1. Easy to operate.

2. Connected to 12V car battery, different voltages, signal lights have different performance:

(1). 0V-4.5V: The product cannot be started, please replace the battery in time.

(2). 4.5V-11.4V: The OK light flashes and the other lights are not lit. The higher the voltage, the faster the flashing frequency. When the voltage reaches 11.4V, the OK light is always on.

(3). 11.5V-11.9V: The LOW light flashes and the OK light is always on. The higher the voltage, the faster the flashing frequency. When it reaches 11.9V, the LOW light is always on and the other lights are off.

(4). 12V-12.5V: MIDDLE light flashes, LOW light is always on. The higher the voltage, the faster the flashing frequency. When it reaches 12.5V, MIDDLE light is always on, other lights are not bright.

(5). 12.6V-13.4V: FULL light flashes, MIDDLE light is always on. The higher the voltage, the faster the flashing frequency. When it reaches 13.4, the FULL light is always on and the other lights are off.

(6). 13.5V-14.4V: GOOD light flashes, FULL light is always on. The higher the voltage, the faster the flashing frequency. When it reaches 14.4V, the GOOD light is always on, and the other lights are not bright.

(7). 14.5V-15.4V: The FAULT light flashes and the GOOD light is always on. The higher the voltage, the faster the flashing frequency. When the voltage reaches 15.4V, the FAULT light is always on and the other lights are off.
