Cobalt gauges have the look and feel of the gauges from back in the day but with a twist of styling. It is at night when these gauges scream 21st Century! The brilliant LED Cobalt Blue light, that shines through the dial of the face to light up the numbers, is easy on the eyes and even easier to read at a simple glance. Perfect for street rods, muscle cars, imports, trucks, etc. Includes a rugged, rubber-lined shock proof strap with mounting base. Operates on standard/electronic and most high performance electronic racing ignitions.
