DC 12V Car Digital Voltmeter - AIMILAR LED Display Voltage Volt Meter Gauge for Car Motorcycle (Red)

Perfect,was just what I was looking for and works flawlessly. Upgraded the 72' C/K 20 to an alternator with an internal regulatior (also from Amazon) the dash gauge wasn't working before the upgrade. Hooked this directly into the ge fuse panel. Is shows 14.2 volts accurately when running. When you turn on the lights, the blower, the blower the voltage never goes below 13.4. I do recommend this little meter and the blue goes good with old blues paint job. It has lasted, easily mounts with adhesive strip to the dash (no holes) and a great price.

I installed this on my ATV to monitor the electrical system voltage. After installing a new stator, flwheel, and voltage regulator it is nice to see the voltage at all times to make sure everything is running correctly. Easy to install, just solder/connect the positive and negative wire to your battery. I soldered them into a fused accessory port and it measures accurately to the tenth of a volt. I verified with my professional Fluke multimeter. The display updates every couple of seconds. Very bright LEDs are easy to read even in direct sunlight. I would highly recommend.

Great product, Easy mount, Bright display, works great on my zero turn to keep a check on my charging system.

I bought this to monitor my battery voltage after an alternator went out on my truck. I have another meter that plugs in a cigarette lighter plug and has two USB plugs on it, but it cycles between voltage, current draw on the USB plugs and temperature in Celsius (which I can't change). I only needed the voltage so I went looking for something else. Despite the reviews I saw saying it was too bright, I said "It can't be that bad". Install was fairly easy. Mine did not come with the double side tape but luckily I keep this around my house. The wires were small as others have noted, but workable. Only took me about 30 minutes to install. Display was easy to read even during full daytime light. I work nights so it is dark out when I head in. First night I started the truck I was blasted from the light. Believe me when I say the photos do not do it justice for the brightness. For a week I had to run with it until I could see what I could do. During that time I thought, "Window Tint". Sadly I could not find any lying around the house so I had to pick up some. I purchased 5% tint which is the darkest they had. A bit pricy as I only needed a piece 3/4" x 2". Therefore I did some testing first. I unrolled the tint from the inside to test without actually "opening" the tint. Amazon is moving my pictures around so I put numbers on them. In the picture #1 I show the full display unfiltered. As you can see, it really lights up the dash. In #2 picture is with one layer of the tint just held over the display. Although it is still lighting up the dash part, you can see some diffusion. #3 picture is with two layers of tint held over the display (part of the "1" only has one layer) and you see a bit more diffusion. I liked what I was seeing. So I went ahead and cut a small piece off and attached it. Currently I am only running one layer of tint. As you can see in #4 picture, it did make a huge difference. Unfortunately I can't see the "V" anymore but that's not a big deal. Although I have not driven yet at night, I am sure this will help a lot. If not, I can always add a second layer. I did drive in full daylight today and was still able to read the display with full sun. In all, I would highly recommend this voltage display. I do wish it had some kind of dimmer control or an auto day/night dimmer. If you do get this meter and have the same issue, I would recommend stopping by a local tint shop and see how much they will sell a small 3/4" x 2" piece of tint for. They will probably just give it to you. Otherwise you can pick some up at any auto parts store and save the rest for another day.

Meter works Fine, easy to read and accurate!

Great and not really bright. Very easy to install

Nice ! Kf400 mule

Worked great for about 10 minutes. Heard a pop from the unit & a small flash of light. Screen went blank & unit smelled burnt. Disconnected tachometer from battery I was testing it on & when I reconnected screen reads 22.2 & doesn't respond.

Muy fácil de instalar, hace la medición correcta en general, la luz no es molesta (depende donde lo instales) y se ve bonito yo tengo la retroililuminacion en Liz blanca y se ve bonito
