The standard MGB instrument set comprised a speedometer, tachometer, combined oil pressure and water temperature gauge, and fuel gauge throughout production. All were Smiths instruments, though the dashboard layout around them changed significantly, from the simple painted panel with toggle switches of the early cars, through the padded dashboard with rocker switches introduced for the 1972 model year, to the final Trinite-covered dashboard with illuminated rocker switches from 1977.
For owners seeking to improve the appearance of their instruments or add supplementary gauges, original instruments can be refurbished with magnolia or silver faces to contrast with and enhance any dashboard, particularly effective when paired with a burr walnut or carbon fibre veneer overlay. Refurbished instruments are available on an exchange basis or by reconditioning the customer's own units. Auxiliary gauges for oil temperature, voltmeter, and clock functions are available to supplement the standard instrument set, providing additional monitoring for owners who want more information about the car's running condition. Chrome instrument bezels are available for owners refreshing the appearance of the existing gauges without a full overhaul.
