The kit ships with the instrument, wiring harness, and installation hardware so you can replace or add a volt gauge without extra sensors. It measures from 8 to 18 volts and triggers a red warning lamp when the voltage drops beneath 11.5 volts, helping you notice battery or charging issues early.\n\n\u003ch3\u003eHow does the WATERWICH voltmeter make monitoring easier?\u003c\/h3\u003e\n\u003cp\u003eThe vivid blue LED and simple digital readout let you check voltage instantly while driving, reducing guesswork about battery state. The voltmeter’s response is immediate, so transient changes and charging behavior are shown in real time.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eBright blue LED display for clear visibility in all lighting conditions\u003c\/li\u003e\n  \u003cli\u003eFast-response digital readout for instant voltage feedback\u003c\/li\u003e\n  \u003cli\u003eRed warning lamp activates under 11.5 volts to indicate low voltage\u003c\/li\u003e\n  \u003cli\u003e52mm (2\") standard bezel fits common dash openings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat electrical range and accuracy can I expect?\u003c\/h3\u003e\n\u003cp\u003eThis gauge is designed for 12V vehicle electrical systems and shows voltages between 8 and 18 volts, covering typical automotive battery and charging ranges.
