Detailed Product Overview

Standard Ignition DS-70 is a headlight dimmer switch for vehicles that use a floor-mounted actuator to change between low and high beams. The robust construction and tested switching operation make it a practical replacement for aging or worn original switches in Ford Bronco, Ford F-150, Ford F-250, Ford F-350, and related Mercury applications. This part number DS-70 also cross-references Carlson 7702 for the same application.

Use this switch when the original floor dimmer no longer responds consistently, feels loose, or creates intermittent headlight beam changes. The DS-70 is designed around the listed connector and terminal style so it matches the electrical interface used in the covered vehicles.

What This Part Helps Fix

• Intermittent or failed high/low beam switching
• Headlights that stay on one beam setting
• Loose or worn floor dimmer pedal feel
• Electrical contact loss from aged switch internals
• Dimmer switch issues on Ford and Mercury floor-mounted applications

Installation Notes and Tips

Verify the vehicle uses a floor-mounted dimmer switch before ordering. Confirm the connector style, terminal count, and 12-volt system match the original part. On vehicles with notes such as w/o Auto Headlight Dimmer, use the fitment details to confirm the correct application before installation.

For best results, inspect the connector, terminals, and surrounding wiring for heat damage or corrosion before replacing the switch. The bolt-on mounting style supports straightforward replacement when the original switch location and interface match the listing.

Quality Assurance

Standard Ignition builds this switch with durable materials and copper alloy conductors to support dependable electrical performance. Each DS-70 is tested to verify both mechanical action and electrical switching function before release.
