Detailed Product Overview

Dorman 901-192 is engineered to replicate the original switch layout and operating feel on supported applications. The switch uses a press-button, rotate-selection, and slider-switch mounting design with no attached lead wires and no wiring harness included. Its plastic housing and knob are selected for a factory-style fit and consistent electrical operation in vehicles such as the Cadillac Escalade, Chevrolet Tahoe, Chevrolet Silverado, GMC Yukon, and GMC Sierra.

This part cross-references OE-style numbers such as 1S1995 and DS968 for the same application. It is a practical choice when the original headlight switch is worn, intermittent, or no longer provides reliable control of exterior lighting and interior dome functions.
