Stinger SVMR Red LED Digital Voltage Gauge 12V with 3-Digit Display for Car Audio Caravan and Secondary Battery Voltage Monitoring The SVMR from Stinger is a 12V red LED digital voltage gauge with a 3-digit display, designed for monitoring primary and secondary voltage circuits in car audio, caravan, and accessory battery installations. The simple 3-wire connection allows straightforward installation to any 12V circuit. The display shows voltages above 15.9V as H for high. The SVMR is the red LED counterpart to the SVMB blue LED voltage gauge. Product overview Monitoring battery and system voltage is an important part of managing car audio and accessory installations, particularly in systems with secondary batteries, solar panels, or high-current amplifiers that place significant demand on the electrical supply. The SVMR provides a clear, accurate real-time voltage reading via a red LED 3-digit display, suited to dashboard, trim panel, and custom installation positions where a red illumination colour is preferred or matches the vehicle interior. Two installation methods are supported: surface mounting to flat panels using the included double-sided tape, or flush mounting into trim panels from the rear for a custom, integrated appearance. The 3-wire hookup is simple to install and compatible with primary vehicle circuits, secondary battery circuits, and solar panel voltage monitoring applications. Features and benefits Red LED 3-digit display: The red LED 3-digit display provides a clear, accurate real-time voltage reading suited to dashboard and custom panel installations where red illumination is preferred or matches the vehicle interior lighting. Two installation options: Attaches to flat surfaces with included double-sided tape for surface mounting, or flushes into trim panels from the rear for a custom integrated installation appearance. Simple 3-wire connection: The easy 3-wire hookup allows straightforward installation to primary or secondary 12V circuits without complex wiring. Broad application suitability: Suited to monitoring primary vehicle battery voltage, secondary battery circuits, solar panel voltage, caravan electrical systems, and any other 12V circuit where real-time voltage monitoring is beneficial.

Technical specs Specification Detail SKU SVMR Brand Stinger Display Type Red LED, 3-digit Voltage 12V High Voltage Display H (above 15.9V) Wiring 3-wire hookup Mounting Options Double-sided tape (surface) or flush panel mount from rear Frequently asked questions What is the difference between the SVMR and the SVMB?Both are 12V digital voltage gauges with a 3-digit display, identical installation options, and the same application suitability. The SVMR has a red LED display and the SVMB has a blue LED display. Select the display colour that suits your vehicle interior or personal preference. Note that the SVMB is confirmed to include a self-calibration pot; confirm with us whether the SVMR also includes this feature before ordering. What does the SVMR monitor?The SVMR monitors and displays real-time voltage on any 12V circuit it is connected to, including primary vehicle battery circuits, secondary battery systems, solar panel circuits, caravan electrical systems, and car audio system voltage. What does H mean on the display?Voltages above 15.9V are displayed as H on the SVMR display, indicating a high voltage condition above the gauge's normal measurement range. This may indicate a charging system fault or overcharging condition and should be investigated. What are the installation options for the SVMR?The SVMR can be surface mounted to any flat panel using the included double-sided tape, or it can be flush mounted into a trim panel from the rear for a custom, integrated appearance suited to professional car audio and accessory installations. Is the SVMR suitable for caravan and solar panel monitoring?Yes. The SVMR is suited to caravan, secondary battery circuit, and solar panel voltage monitoring applications in addition to primary vehicle and car audio system voltage monitoring.
