The Cobalt Series features a black dial face, anodized bezel, white numbering, and blue accents. At night, an explosion of Cobalt blue light shines through the dial and into any interior scheme, from stock to shock. A glowing red gauge pointer provides clear contrast and visibility. Lit using LED technology, the Cobalt Series offers a lifetime of super cool lighting. Includes 1/8in. NPT sender, 3/8in. and 1/2in. NPT fittings.
