DS4210 DC 12V 24V Car Voltmeter with LED Digital Display Panel, Waterproof Voltage Gauge Meter with Blue Light
Nice bright display and easy to mount. Our meter is mounted in a caravan and the display is too bright for the situation. But all in all, a good meter.
Been on the car for 2 weeks. The bottom blue lights that make up the bottom horizontal lines for the numbers have started getting dimmer and going out. have to tap the display to get them to come back on. Appears to have a loose connection or high resistance join inside the unit.
After 4 weeks the voltage is no longer reading the correct voltage, checked at terminals on back with multimeter and out by 1-2 volts from what is displayed
