OE-Style Headlight Dimmer Switch

Standard Ignition CBS2448 is a direct-fit headlight dimmer switch for restoring proper lighting control in select Cadillac applications. It is built for the 2016-2017 Cadillac CT6 and 2017 Cadillac XT5 with automatic high beam and without fog lights, making it a focused replacement for a faulty combination switch.

Standard Ignition CBS2448 is engineered with copper alloy conductors for strong electrical conductivity and low resistive loss. The switch is fully tested for mechanical and electrical performance, and its OE-style design supports proper fit, form, and function during replacement.

  • Direct-fit OE replacement for the headlight dimmer and combination switch function
  • Black plastic housing with rectangular female connector
  • Blade terminals with 11 terminal positions
  • Includes main light, running light, turn signal, latching high beam, and momentary high beam flasher functions
  • Displayed indicator markings for clear driver operation
  • New switch construction for service replacement

Vehicle Fitment

  • Fits 2016-2017 Cadillac CT6, N/A, w/o Fog Lights; w/ Automatic High Beam
  • Fits 2017 Cadillac XT5, N/A, w/o Fog Lights; w/ Automatic High Beam

This part cross-references Dorman (e.g., 23328819) for the same application.

Common Replacement Reasons

  • Headlights do not switch between low and high beam correctly
  • Turn signal or combination switch functions stop responding
  • High beam flasher or latching high beam operation becomes intermittent
  • Indicator markings or switch feel no longer operate as expected
  • Electrical switching issues traced to the steering column switch assembly

Installation Notes

Verify connector shape, terminal count, and vehicle options before installation. This switch uses a clip attachment method and a single rectangular female connector, so matching the original configuration is important for proper installation on the Cadillac CT6 or Cadillac XT5.

Quality Assurance

Standard Ignition tests each switch for mechanical and electrical switching performance. The copper alloy conductor design and OE-style construction are intended to meet the demands of professional service replacement and restore reliable lighting control.
