Additional Details ------------------------------ Product description: The HDX-55C-K (black alloy style) is compatible with 1955-56 Chevy Cars. This was one of the first direct-fit applications offered by Dakota Digital, so it was only natural to create an HDX system for the icon. A large TFT display lets you expand upon the six analog gauge readings, all installing in to your stock or reproduction bezel. Bezel is NOT included, shown for visual/presentation purposes only. System uses OEM or reproduction style bezel. Each HDX system allows the user to select independent illumination colors for the gauge readings and needles, as well as the message centers. Calibration and personal settings are manipulated with the built-in, capacitive-touch buttons, or the Bluetooth app for Apple and Android devices. Each needle hub is black nickel plated spun-aluminum to match the buttons. All HDX instrument systems feature dead-faced (hidden) indicators (turn signals, high beam, check engine, cruise control, parking brake, plus two user-definable), and a red, settable warning light for each gauge. With our central control box, installation is greatly simplified with vehicle-harness sourced signals and supplied, solid state sending units connecting cleanly to their respective terminal. RGB Backlighting: Set your own lighting colors to match your paint or current mood. Over 30 User-Selectable Display colors available. Select backlighting colors for the needles, digital display and printed gauge readings independently, or choose from one of 12 preset lighting themes. Analog Gauges: Speedometer - 0-160 MPH. Split scale provides resolution of a 120MPH speedometer, with top end range of 160MPH Tachometer - 0-8000 RPM Oil Pressure - 0-80 psi Water Temperature - 100-260ºF Fuel Level - E, 1/4, 1/2, 3/4, F Voltmeter - 9-17 VDC
