Standard Ignition DS-188 Headlight Switch

Headlight Switch for Ford Bronco and Econoline

Standard Ignition DS-188 is a 12-volt headlight switch built for direct, snap-fit installation in select Ford trucks and vans. It uses copper alloy conductors for strong electrical conductivity and low resistive loss, with a metal and plastic finish suited to service replacement work.

Fits 1965-1977 Ford F-100, 1965-1975 Ford F-250, and 1965-1975 Ford F-350, along with select Ford Bronco and Econoline applications. Standard Ignition DS-188 is a practical replacement for restoring headlight control on older Ford platforms.

Key Features

• Headlight switch function for 12-volt systems
• Direct, snap-fit attachment method
• Female rectangular connector with 8 male blade terminals
• Metal color with metal and plastic finish
• Copper alloy conductors for efficient electrical transfer
• 100% tested for mechanical and electrical switching performance

Detailed Description

The DS-188 headlight switch is engineered for service replacement on classic Ford applications, including Bronco, E-Series vans, and F-Series trucks. Its direct-fit design supports straightforward replacement of a worn or failing switch, while the 8-terminal blade layout and rectangular connector help maintain proper circuit engagement. Standard Ignition builds this switch with durable materials and conducts full testing to verify switching function before release.

This part cross-references Standard Ignition DS188T for the same application.

Common Problems It Can Help Solve

• Headlights that do not turn on or stay on consistently
• Intermittent lighting caused by worn internal switch contacts
• Loose or unreliable electrical connection at the dash switch
• Dim or unstable headlight operation from high resistance in the switch
• Failure of the original switch in older Ford Bronco, F-100, F-250, or F-350 models

Installation Notes and Tips

Verify connector style, terminal count, and vehicle serial-number notes before installation. This switch uses a female rectangular connector with male blade terminals and direct snap-fit attachment, so matching the original dash configuration is important for proper fitment. Confirm 12-volt system requirements and compare the existing switch to the replacement before final assembly.

Quality Assurance

Standard Ignition uses high-grade materials and copper alloy conductors, then tests each switch for mechanical and electrical performance. That process supports consistent operation in demanding service environments and helps ensure dependable headlight control on compatible Ford applications.
