Ultra-Nite gauges from Auto Meter include blue anodized bezels and are designed for the extreme conditions of dirt track racing. They are 100% waterproof, so they can be hosed off after the races and the sealed case keeps moisture and debris out. Plus, the Ultra-Nite's glow-in-the-dark face eliminates the need for a light and battery.
Designed to mount into your dash. Operates on 4, 6, or 8 cylinder engines with points, electronic, and most 12V high performance racing ignitions.
