WATERWICH Oil Pressure Gauge 0–150 PSI 2" (52mm) DC12V Kit with Blue Backlight & Red Warning

WATERWICH 2" oil pressure gauge kit is a complete DC12V 0–150 PSI monitoring solution that gives clear, backlit readings and includes sensor, harness, and instructions for easy installation.

This compact 52mm instrument is designed for automotive use — cars, SUVs, trucks, and light commercial vehicles — to help drivers keep a constant eye on engine oil pressure. The bright blue illumination makes the dial easy to read at night while an integrated red warning indicator alerts you when pressure falls below a preset threshold. The kit contains everything needed to replace or add an oil pressure gauge: the instrument, a matched pressure sensor, a wiring harness, and simple installation guidance.

How does the WATERWICH gauge display oil pressure clearly in all lighting?

The gauge uses a vivid blue LED backlight to ensure the dial is legible from multiple angles, day or night. The digital-style display and pointer are optimized for quick glances while driving, and a red warning lamp provides an unmistakable low-pressure alert.

• Blue LED backlight for high night visibility
• Clear analog-style dial with digital accuracy
• Red warning light triggers under 18 PSI for fast attention
• Compact 52mm diameter fits common dashboard openings

What pressure range and accuracy can I expect from this gauge?

The WATERWICH gauge monitors oil pressure across a 0–150 PSI span, covering typical passenger vehicle and light-truck requirements. The calibrated sensor and instrument are matched as a kit to provide consistent readings and a reliable reference for engine operating conditions.

• Full scale: 0–150 PSI to cover low and high-pressure events
• Red warning setpoint below 18 PSI to highlight dangerously low oil pressure
• Sensor included to ensure proper compatibility and calibration
• Designed for DC12V electrical systems common in most vehicles

How easy is installation and what does the kit include?

The kit is supplied with the gauge, the matched pressure sensor, a wiring harness, and installation instructions so you won’t need to source extra parts. The sensor threads into a pressure port or adapter, and the harness plugs to the gauge and vehicle power, making it suitable for direct replacement or aftermarket installation.

• Complete kit: gauge, sensor, harness, and instructions
• No separate sensor purchase required; compatible sensor included
• Plug-and-wire harness reduces installation time and errors
• Fits standard 2" (52mm) dashboard openings for many vehicles

Will this gauge work with my vehicle and electrical system?

The gauge is designed for DC12V systems used by most modern cars, SUVs, and light trucks. Its universal 2" diameter is a common aftermarket size, but confirm your dash opening and sensor thread compatibility before ordering to ensure fit and function.

• Power requirement: DC12V, up to 0.3A (maximum)
• Universal 52mm body fits many aftermarket dash mounts and pods
• Sensor thread and fittings included for typical oil ports or adapters
• Suitable for cars, SUVs, trucks, and similar vehicles with 12V systems

Who is this for: The WATERWICH 2" oil pressure gauge kit is aimed at vehicle owners, DIY installers, and professional technicians who want an accurate, easy-to-read, and complete oil pressure monitoring solution. It suits anyone adding a gauge to an older vehicle, replacing a worn instrument, or fitting a secondary gauge for performance tuning and routine engine monitoring. If you need a compact, illuminated gauge that arrives ready to install with a matched sensor and harness, this kit is built to meet those needs.
