AUTO METER Autogage Tachometer 3.75 in Black Dial & Bezel — 2–4 Pulse, Incandescent Perimeter Lighting

The AUTO METER 2300 Autogage is a compact, 3.75-inch mechanical-style tachometer engineered to deliver clear RPM readings for street and performance vehicles.

This compact tachometer pairs classic styling with practical compatibility, giving drivers an easy-to-read rev counter that fits many dashboards. It combines a black dial and matching bezel with conventional incandescent edge lighting for visible night-time viewing, and accepts common ignition pulse patterns so it works with a wide range of stock and aftermarket ignition systems.

How does this tachometer display RPMs clearly in low light?

The 2300 Autogage uses traditional incandescent lighting positioned around the dial's perimeter to keep numbers and needle visible in darkness without harsh glare. The black dial and bezel provide contrast that improves readability at a glance.

• Perimeter incandescent illumination for even glow
• High-contrast black dial and bezel for quick reading
• 3.75-inch diameter suited to tight dash locations

Will this unit work with my vehicle's ignition system?

This model is designed to accept 2- to 4-pulse ignition inputs, handling common setups used on 4- and 8-cylinder engines. It’s compatible with points-style distributors, electronic ignitions, and most 12V high-performance race ignitions when wired correctly.

• Accepts 2–4 pulse signals (suitable for 4–8 cylinder engines)
• Works with mechanical points and most electronic ignitions
• Compatible with many high-performance 12V racing ignition systems

Is it suitable for different electrical systems and vehicles?

The Autogage is rated for both 12 and 16 volt environments, so it functions across the majority of street cars and many race car electrical setups. That voltage tolerance reduces the need for additional converters in most installations.

• Operates on 12V and 16V electrical systems
• Works in typical street vehicles and many race-spec setups
• Compact size eases installation in crowded instrument panels

What are the installation and usage considerations?

Installation requires tapping into the ignition pulse signal and connecting power and ground; the compact form factor helps place the gauge in tight locations. No special lighting harness is necessary beyond a standard incandescent supply for the bezel illumination.

• Requires ignition pulse input, power, and ground connections
• Standard incandescent lighting wiring for dial illumination
• 3.75" diameter fits many aftermarket pods and panels

Who is this for: The AUTO METER 2300 Autogage suits budget-conscious enthusiasts who want a reliable, easy-to-read tachometer with classic looks. It's a good fit for owners of street-driven cars and many race vehicles that use 12–16 volt systems and common ignition types, as well as builders who need a small-diameter gauge to conserve dash space. If you want straightforward RPM monitoring in a compact package with traditional lighting and broad ignition compatibility, this model provides a practical, cost-effective solution.
