2 Pieces DC 4 to 28V Car Digital Voltmeter 12V Voltage Meter Car Audio Gauge LED Display 12V Waterproof Voltage Gauge Meter for Motorcycle(Red Light)

I’ve used these multiple times over the past years and they work great. Great accuracy and durable in any weather condition. Perfect size and brightness.

I love these things and add them to many DC machines, vintage cars, rvs, boats, solar applications. They're easy to read and can be stuck anywhere with a little velcro.

Works good, I used it to monitoring my motorcycle charging voltage.

The media could not be loaded. Extremely easy to read having large digital display. When lucky enough to get a good one, they are accurate within about one-to-two hundredths of a volt — as measured with my $500 Fluke ET-88 multimeter. Comes with adhesive mounting tape. Has 3-foot wire leads appearing to be about 22-26 AWG gauge wire. With small gap in housing where wires exit the plastic housing, a dab of silicone gel should seal it to becoming waterproof. One downside is there is no ON-OFF switch, but perhaps unnecessary since another Reviewer on Amazon noted the amount of the slight draw when connected constantly. However, the 2nd digital display meter was not as accurate as the first one; see attached pic. I ranked this a 4-star because of the 2nd display not being accurate enough —- close but not as accurate as the first one. They come two display meters to a package..I have included pics and video to demonstrate my claims in this review. I highly recommend this product, even if you have to return-and-reorder until you get two good ones. However, I have had this product only a few days, so I cannot attest to its longevity yet. I'll update this review if the product later fails in some way in future.

Works, accurate to the 1st decimal place, easy to install. good proce.

Great product works amazing

Perfect fit for my 1948 Pickup 6 volt

One of the items worked fine and the other one did not work at all
