Product Details
DS-1377 is a replacement headlight switch for 1999 Ford Expedition, F-150, and F-250 models listed in the fitment data. The switch is built with durable materials and a connector layout designed for service work, helping restore reliable lighting control when the original switch shows wear, intermittent operation, or electrical contact issues. Standard Ignition DS-1377 is intended for vehicles without Auto Headlights and is listed as compatible with trucks and SUV equipped with Fog Lights.
Common Issues It Can Solve
- Headlights that do not turn on or off correctly
- Intermittent lighting control from worn internal contacts
- Dim or inconsistent switch response caused by electrical resistance
- Broken or loose switch connection at the dash harness
- Fog light control concerns on supported 1999 Ford applications
Installation Notes and Tips
Verify the connector style, terminal count, and vehicle equipment before installation. This DS-1377 switch uses a female rectangular connector with 12 male blade terminals and direct snap-fit attachment, so matching the original switch layout is important for proper operation. Confirm the vehicle is not equipped with Auto Headlights, since that configuration is excluded from the listed fitment.
Quality Assurance
Standard Ignition builds this switch with robust materials and copper alloy conductors, then tests each unit for both mechanical action and electrical switching performance. That validation helps support consistent operation in daily service use.
