Description: Easily identified by their anodized blue exterior, these Ultra-Nite analog gauges from AutoMeter offer unique features needed in many forms of racing (not designed for street use). The luminescent dial glows at night for dimly lit tracks when no battery is available to light conventional gauges. A sealed water-resistant case keeps moisture and debris out, and lightweight anodized aluminum fittings on the temperature gauges are ideal for Sprint Car racing. The 2 5/8 in. dials are available to monitor four different functions; they're offered in multiple gauge ranges, in dry and liquid-filled models.
