Raceworks gauges contain an analogue face, with digital circuitry. They offer many motorsport oriented functions, all of which are accessed by a single button on the face. They are perfect for vehicles that don't get used often, and may have the power killed completely in between infrequent drives, because all settings are hard coded into memory. They offer daisy chain wiring, meaning common wires such as power, ground and illumination only need to be connected to one gauge in a set, and a simple piggyback cable runs between each gauge. All Raceworks gauges are suitable for 12V applications only. Backlight colours are Red, Green, Blue, Yellow, Purple, Teal, Cool White, Pink, Warm White and Orange.
