VDO Vision Instruments deliver world-class accuracy, reliability, and technology at very competitive pricing. These precision instruments feature stepper motor technology or air core movements for smooth, accurate performance and long-life dependability. Our Spin-LokTM mounts make installation fast and easy while providing a full 360º of mounting force, to prevent panel warping and gauge rotation. Vision gauges incorporate our TriopticTM through-dial illumination for maximum nighttime visibility. Optional light diffusers allow the dial illumination color to be changed to red or green.
