[[Chrysler Corporation]] offered "Mirror-Matic" as optional equipment on nearly all of its US models from 1959 through 1961. {{cite book | title = MoPAR PASSENGER CAR PARTS LIST 'M' SERIES 1959, SEPTEMBER 1958| publisher = CHRYSLER CORPORATION SERVICE PARTS & ACCESSORIES SUPPLY DIVISION | page = 23-16 | date = September 1958 | location = Detroit MI }} When the headlights were on and the Mirror-Matic sensitivity was set to anything except "Off", an electromechanical solenoid flipped the prismatic mirror between its night & day positions as needed based on the input from a single, rear-facing light sensor positioned behind a clear circle in the mirror face. For model year 1960 Mirror-Matic was improved by using an adjustable sensitivity wheel (1-10 & Off) instead of having just "Hiway", "City", & "Off" for light sensitivity settings. Because it was only offered for 4 years, it is generally believed that it did not sell well, although specific sales figures are unknown.
