Headlight Switch for 1968-1993 Cadillac DeVille & More - Standard Ignition DS-186

Take charge of your classic Cadillac's lighting with the Standard Ignition switch DS-186, a headlight switch that turns the headlights on and off at the driver's command. It is a direct-fit replacement for many vehicles, among them the 1968-1981 Cadillac Fleetwood, 1968-1993 Cadillac DeVille and 1987-1992 Cadillac Brougham. See the "Vehicles it fits" section for the full list and engine details on each application.

• Quality control from start to finish: As a global manufacturer of original equipment ignition products, Standard Ignition keeps complete quality control over the manufacturing process, from componentry to the finished product.
• Copper alloy conductors: Provide superior electrical conductivity with low resistive losses.
• 100% tested: Each switch is tested to verify both its mechanical and electrical switching performance.
• Built for the service bay: A robust design and high-grade materials meet the stringent demands of today's service professionals, backed by decades of industry-leading research and development focused on what technicians need.

The headlight switch is the control the driver uses to operate the headlights. If a worn or failed switch is the cause of headlights that won't come on, cut out intermittently, or flicker, the DS-186 replaces it.
