AUTO METER Ultra-Lite Electric Water Temperature Gauge — Silver dial, 100–250°F range, fast-response

The Auto Meter 4337 Ultra-Lite Electric Water Temperature Gauge is a lightweight, race-proven instrument that delivers fast, easy-to-read engine water temperature readings in a compact package.

Designed for drivers who need reliable, visible temperature feedback without adding weight or bulk, this silver-dial gauge pairs high-contrast orange pointers with traditional incandescent perimeter lighting for clear nighttime and daytime visibility. The Ultra-Lite series is built to the demands of both street and race cars, offering compatibility with 12V and 16V electrical systems and an air-core electric movement that keeps fluids out of the vehicle while providing responsive readings. A complete kit is included so you can install quickly with commonly used senders and adapters.

How quickly and accurately does this gauge report water temperature?

The Auto Meter Ultra-Lite uses an air-core electric instrument combined with an included 1/8" NPT temperature sender to give prompt, repeatable readings without routing coolant through the dash. The electric design translates sender resistance into needle position rapidly, making it suitable for performance driving where trends matter.

• Range: 100–250 °F for typical engine temperature monitoring
• Air-core electric movement for fast needle response
• Includes 1/8" NPT sender for direct electrical sensing

Will it work with my car’s electrical system and existing fittings?

This gauge is built for broad compatibility: it operates on both 12- and 16-volt systems, which covers nearly all street cars and many race applications. The kit includes adapters and hardware so you can fit common thread sizes without sourcing extra parts.

• 12V and 16V compatible — fits most vehicle electrical setups
• Includes 3/8" and 1/2" NPT adapters for flexible installation options
• Bulb and socket assembly plus red and green bulb covers for indicator customization

How easy is installation and night visibility?

Auto Meter supplies a complete installation kit and clear instructions to streamline fitment. Traditional incandescent lighting rings the dial perimeter so the orange pointer contrasts sharply against the silver face for improved legibility in low light.

• Complete gauge kit with mounting hardware and detailed instructions
• Perimeter incandescent light for consistent dial illumination
• High-contrast orange pointer and silver dial for fast reading

What accessories and protections are included with the gauge?

The 4337 kit arrives with the practical components needed for a clean, race-ready install and allows simple customization of warning lighting. Auto Meter’s design philosophy minimizes intrusion into the vehicle by keeping hazardous fluids out of the cabin and relying on electrical sensing instead.

• Includes sender, adapters, bulb/socket assembly, and mounting hardware
• Red and green bulb covers let you set visual warnings or match dash color themes
• 1-year limited warranty from Auto Meter for coverage against defects

Who is this for: The Auto Meter 4337 Ultra-Lite Water Temperature Gauge is aimed at drivers, racers, and builders who want a lightweight, dependable temperature instrument with clear readability and straightforward installation. It’s ideal for performance street cars, track cars, hot rods, and anyone retrofitting a classic dash who values fast electrical sensing, minimal plumbing, and modular mounting hardware.
