Lido Pro Series gauges are fog-free with a stylish domed glass that sheds water, resists scratching, and looks great anywhere. Tough, magnetically-shielded, silicone-dampened vector movements are the ultimate in accuracy and reliability. The Lido's polished stainless steel bezel looks great in most dashes. Black text on a clean white background offers maximum daylight readability, while night visibility is provided by white perimeter and red through-dial lighting. Requires 2-1/8" dia. hole.
