Detailed Description

Standard Ignition DS-739 is engineered for vehicles that rely on a multifunction steering column switch to control headlights, high beams, turn signals, and wiper functions. The robust housing and high-grade materials are paired with copper alloy conductors to support strong electrical conductivity and low resistive loss. Each unit is tested for both mechanical action and electrical switching performance before release.

This part is used across a wide range of Chrysler, Dodge, Jeep, and Plymouth models, including Dodge Ram 1500, Ram 2500, Ram 3500, Dakota, Durango, Viper, Jeep Cherokee, and Jeep Grand Cherokee applications. It also serves select Plymouth Prowler and Chrysler LeBaron applications where the original combo switch assembly uses the same configuration. Standard Ignition DS-739 is a direct replacement for drivers searching for a Dodge Ram headlight dimmer switch, Jeep Grand Cherokee multifunction switch, or Dodge Dakota turn signal and wiper switch.
