After extensive research and development, Auto Meter's Lunar Series give you luminescence in revolutions per minute. The Lunar Series of competition instruments features a bright white dial face, black numbering and increments, and a silver bezel. When lit for night time use, the Lunar 10,000 RPM Shift-Lite tachometer and gauges emit a futuristic green glow, provided by a thin layer of phosphor that's exposed to a mild electric charge. The lighting is wired through the OEM switch and light intensity is controlled in the same way the stock dash lighting would be. Lunar will turn any custom interior into mission control.
