It uses the Amega black dial design with red graduations, white numerals, and a vivid white pointer staff for high contrast in bright sun or low light. The face is protected by a scratch resistant curved glass lens set into a black, near-flush bezel for a clean, low-profile look on the dash. The gauge includes both perimeter and thru-dial lighting so it stays readable at night, and the scale is marked with U.S. And metric graduations along with ISO symbols where appropriate.\u003c\/p\u003e\u003cp\u003eInstallation requires a 2.13 inch mounting hole. The Amega line has been a popular Sierra dial style since its debut in 1986, and the 57901P voltmeter is also offered as part of larger Amega instrument sets alongside matching speedometers, tachometers, and fuel\/temperature gauges for a coordinated dash layout.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e
