Standard Ignition DS-197 Headlight Switch

Headlight Switch for Ford Trucks and Vans

Restore reliable headlight control with Standard Ignition DS-197. This 12-volt headlight switch uses a direct, snap-fit attachment method and an 8-blade terminal layout for a secure electrical connection in the vehicle’s lighting circuit.

Compatible with select Ford Bronco, F-100, F-150, F-250, F-350, and Econoline applications, this switch is built with metal and plastic construction, a metal finish, and copper alloy conductors for consistent electrical conductivity.

Key Features

Detailed Description

Standard Ignition DS-197 is a replacement headlight switch engineered for service work on older Ford trucks and vans. It is a direct-fit electrical switch with a female rectangular connector, male blade terminals, and a 12-volt rating, making it suitable for restoring headlight operation where the original switch has worn contacts, intermittent output, or failed switching action. This part cross-references Standard Motor Products (e.g., DS-197) for the same application.

Common Problems It Can Solve

• Headlights that do not turn on or shut off properly
• Intermittent headlight operation caused by worn switch contacts
• Heat-related electrical resistance in the lighting circuit
• Loose or unreliable switch engagement at the dash
• Dim or inconsistent headlight output from poor switch conductivity

Installation Notes and Tips

Verify the connector shape, terminal count, and vehicle serial-number break before installation. Match the existing switch to the 8-blade terminal layout and direct, snap-fit mounting style to confirm proper fit in the dash assembly. Inspect the connector terminals and wiring for corrosion or heat damage before connecting the replacement switch.

Quality Assurance

Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for mechanical and electrical switching performance. That process supports consistent operation in service applications such as Ford Bronco, F-Series trucks, and Econoline vans.
