## Description

Product description ALARM FUNCTION Display shows “L L L” to warn when voltage is below 4 Volt. Display shows “H H H” to warn when voltage is over 28 Volt. WATERPROOF Smooth surface design. PVC MATERIAL With transparent shell for watching the screen clearly. Motorcycle RV Ship Substation automation

Review: Excellent! - Worked perfect for my power supplies on my radios. Easy to install and came with double stick tape. The wires are a real small tiny gauge. Tinned the tips and soldered them to existing power wires. Red seemed it would be a little easier on the eyes at night as they are bright. Definitely recommend them for ham radio power supplies.
Review: Easy to see, easy to read -- on the dashboard. - These work great stuck on the dashboard. Large enough to see easily. I have one on a 'cigarette lighter' plug and it shows the car battery when the ignition is on; I have the other connected to a portable battery in the car which I use to power my ham radio rig, and now I always know when that little battery needs to be charged.

### ⭐⭐⭐⭐⭐ Excellent!
*by S***S on April 30, 2026*

Worked perfect for my power supplies on my radios. Easy to install and came with double stick tape. The wires are a real small tiny gauge. Tinned the tips and soldered them to existing power wires. Red seemed it would be a little easier on the eyes at night as they are bright. Definitely recommend them for ham radio power supplies.

### ⭐⭐⭐⭐⭐ Easy to see, easy to read -- on the dashboard.
*by J***R on May 26, 2026*

These work great stuck on the dashboard. Large enough to see easily. I have one on a 'cigarette lighter' plug and it shows the car battery when the ignition is on; I have the other connected to a portable battery in the car which I use to power my ham radio rig, and now I always know when that little battery needs to be charged.

### ⭐⭐⭐⭐⭐ The white LEDs are nice and bright
*by K***L on November 5, 2025*

I got the white LED so that I could put it on a pole outside my solar battery bank. Measured it against a standard VOM, and was within .05 bolts of the VOM. Excellent results. Now I can check on my battery levels at night to see if I need to switch back to the utility or I need to go crank the generator. Some complain about the small wires. They are 22 gauge wires which are now industry standard for most all of your instrumentation wiring. It works excellent. Voltage is very accurate. I bought two , one is a backup.
