Gauge Accessories

What Gauge Accessories Do for Your Dash

Gauge accessories handle everything around the gauge itself: mounting, trim, wiring, and alerts. They turn a set of loose gauges into a clean, readable, working instrument panel. Get them right, and your gauges sit square, stay easy to see, and report reliably.

Shop by the job you need done: framing, fitment, alerts, or wiring. Each section below covers what to look for in that part type.

Gauge bezels frame each gauge and hold it to the dash. Dash bezels replace the factory instrument panel on specific vehicles. Warning lights flag a problem the moment it happens, and harnesses connect your gauges to power, ground, and senders.

If you're still choosing gauges, settle that first, since gauge diameter drives most accessory choices. This category carries more than 900 items from brands including Auto Meter, Longacre Racing, and Reversion Raceworks. For senders, mounts, and more, browse all gauges and accessories.

How To Choose a Gauge Bezel

Choose a gauge bezel by matching its diameter to your gauge, then pick the profile and finish that suit your dash. The bezel mounts between the gauge and the dash, so the wrong size won't fit. Get the diameter right, and the rest comes down to looks and viewing angle.

Most aftermarket gauges come in 2-1/16" (52mm) or 2-5/8" sizes. Larger tachometers and speedometers typically run 3-3/8". Measure your gauge before you order, then use the diameter filter to narrow results.

Flat bezels sit flush on a flat panel. Angled bezels tilt the gauge toward you, which helps on panels that don't face the driver. Finish options include polished, black anodized, clear anodized, and powdercoat.

Replacing a scratched or worn trim ring? Replacement gauge bezels let you refresh a gauge face without buying a new gauge. For help matching sizes, styles, and functions, read our gauge selection guide.

Dash Bezels for Classic Cars and Trucks

A vehicle-specific dash bezel replaces or restores the factory panel that holds your instruments. It's the go-to fix when your original bezel is cracked, faded, or cut up from past gauge swaps.

Options here cover popular classic platforms. Examples include a 1967-68 Camaro center dash bezel, a 1969-1972 Chevy/GMC C/K truck dash bezel, and a 1966-1977 Ford Bronco instrument gauge bezel. You'll also find a 1968-69 Oldsmobile Cutlass/442 dash bezel set.

Truck owners can choose a 1981-1987 Chevy/GMC truck dash bezel insert or a 1988-1994 Chevy OBS truck blank dash bezel. A blank bezel gives you a clean panel for a custom gauge layout.

Digital dash bezels adapt aftermarket digital displays to factory dashes, with fitments for the 1997-2004 C5 Corvette and 1989-1994 Nissan 180SX. If you'd rather keep your factory dash intact, look at gauge mounts and gauge panels instead.

Warning Lights and Warning Light Kits

A warning light gives you an instant visual alert when a critical reading crosses a set limit. It's a smart backup for a gauge you can't watch every second, especially at the track. Oil pressure and coolant temperature are popular readings to back up with a light.

This category covers oil, coolant, charging, and brake alerts, with options including:

• Oil pressure warning light kits with an adjustable 15-50 psi trigger point
• Water temperature warning light kits that trigger at 230°F
• Pro-Lite warning lights with a red lens and night cover
• Amber warning light assemblies
• Alternator warning light modules
• Parking brake warning signal kits

Mount the light directly in your line of sight so you catch it right away. Shift lights work the same way for rpm, so check out our shift and warning lights to build a complete alert setup.

Gauge Wiring Harnesses and Digital Dash Integration

A gauge wiring harness gives you organized connections between your gauges, power, ground, and senders. It saves you from splicing a rat's nest of wires behind the dash.

Dash gauge harnesses here cover tach, temperature, fuel, oil, and voltage gauges. You'll also find an under-dash harness for factory gauges and a fuel rail pressure harness for 2001-2010 GM applications. VDO offers an 8-pole retrofit harness for its Viewline gauges.

Each gauge still needs a signal source, so pair your harness with the right gauge sending units. Not sure which style fits your build? Our guide to electric vs. mechanical gauges breaks down the differences.

Running EFI? A CAN bridge lets a compatible EFI system feed engine data to your gauges. Pair it with a digital dash bezel for a modern instrument setup in a classic or import dash.
