AUTO METER Ultra-Lite Electric Water Temperature Gauge 4337 — Silver Dial, 100–250°F, Incandescent Lighting

The Auto Meter 4337 Ultra-Lite is a lightweight electric water temperature gauge with a high-contrast silver dial and orange pointer engineered for quick, reliable engine temperature monitoring in street and race cars.

This compact instrument blends race-proven air-core movement technology with a clear, easy-to-read face and robust compatibility across 12V and 16V systems. The 4337 offers a 100–250 °F measurement span, incandescent perimeter lighting for nighttime visibility, and a full accessory kit so you can install it without hunting for extra pieces. Built for drivers who need fast readings and minimal weight, it keeps fluid contacts out of the cockpit while delivering a precise electrical signal to the gauge.

How will this gauge improve visibility at night?

The gauge uses traditional incandescent lighting that surrounds the dial, giving an even glow around the face. The silver background with a bright orange pointer creates strong contrast so needle position is readable at a glance under varied lighting conditions.

• Perimeter incandescent lamp provides uniform illumination
• High-contrast silver dial and orange pointer for quick reads
• Red and green bulb covers included to match instrument panel themes

Will it work with my car’s electrical system?

Yes — the 4337 is designed for both 12-volt and 16-volt setups, making it suitable for most street machines and many race applications. The gauge’s air-core electric movement offers fast response without requiring mechanical fluid routing through the gauge body.

• Compatible with 12V and 16V electrical systems
• Air-core electric mechanism for rapid, accurate indication
• Keeps engine coolant and other fluids outside the vehicle’s interior

What’s included in the kit and how easy is installation?

The complete gauge kit supplies the sender, adapters, lighting parts, mounting hardware, and instructions to streamline installation. Included components cover common thread sizes so you won’t need to source extra fittings for many applications.

• 1/8" NPT temperature sender for electrical signal input
• 3/8" and 1/2" NPT adapters for flexible plumbing options
• Bulb, socket assembly, colored covers, mounting hardware, and instructions

What temperature range and accuracy can I expect?

The instrument reads from 100 to 250 °F, suitable for monitoring typical coolant temperatures in performance and street engines. The electric sender and air-core movement provide quick needle response to changes in operating temperature.

• Measurement span: 100–250 °F
• Fast-reacting air-core electric movement
• Designed for racing durability and street reliability

Who is this for: The Auto Meter 4337 Ultra-Lite is aimed at performance drivers, racers, and enthusiast street-car owners who want a lightweight, responsive water temperature gauge with clear night visibility and easy installation. It’s a strong choice when you need a compact, race-capable instrument that avoids fluid-filled internals and fits commonly used electrical systems.
