Detailed Description

This Standard Ignition CBS-1642 headlight dimmer switch is engineered as a replacement combination switch for the 2005-2007 Subaru Legacy. It is designed with the correct connector style, terminal layout, and switch functions needed to restore headlight dimming and turn signal operation at the steering column. The assembly includes the main light operator, latching high beam control, momentary high beam flasher, and turn signal control, while omitting cruise control and fog light functions.

For buyers searching for a Subaru Legacy headlight dimmer switch, Subaru Legacy combination switch, or CBS-1642 replacement switch, this part provides a direct-fit electrical solution for the listed vehicles. This part cross-references Subaru 83115AG040 and Dorman DL7042 for the same application.

What It Helps Resolve

  • Inoperative or intermittent headlight dimmer control
  • High beam switch that does not latch or flash properly
  • Turn signal control issues at the steering column
  • Worn, cracked, or electrically unreliable original switch assembly
  • Loss of normal main light switching function

Installation Notes and Tips

Verify vehicle fitment before installation, especially on Subaru Legacy models equipped with fog lights, since this application is not compatible with that configuration. Match the connector shape, terminal count, and switch layout to the original part before removal. Because this is a bolt-on electrical switch, careful alignment and secure connector engagement are important for proper operation.

Quality Assurance

Standard Ignition supplies this part as a new replacement switch built to match the listed electrical and functional requirements for the specified Subaru Legacy applications. Confirm the part number CBS-1642 and vehicle configuration before installation to ensure correct application.
