SREUOIL 52mm Water Temperature Gauge — 7-Color Tint, 100–300°F, 1/8 NPT Sensor

Upgrade your dashboard with precise visibility

The SREUOIL 52mm Water Temperature Gauge is designed to illuminate the coolant temperature path in your vehicle’s radiator system. A magnified tinted lens reduces glare, allowing you to read the dial at a glance as the engine hums along.

Enjoy a personalized display with seven solid color options. The illuminated red needle sits against a blue LED backdrop, and a convenient lens button lets you switch colors to match your dashboard lighting or to create a distinctive interior style. This small touch can make late-night checks feel less strained and more intuitive.
