Detailed Description

Standard Ignition CBS2447 is engineered as a replacement headlight dimmer switch for Cadillac CT6 and Cadillac XT5 models listed above. It supports the lighting controls commonly handled by the combination switch, including main lighting, fog lights, running lights, and high beam operation. The design uses copper alloy conductors to help maintain low-resistance electrical flow, while the OE-style construction supports a proper restoration of a faulty switch assembly. This part cross-references Dorman (e.g., 23328821) for the same application.

What It Helps Fix

• Intermittent or inoperative headlight dimmer function
• Faulty high beam or flash-to-pass operation
• Nonworking fog light or running light control
• Worn switch feel or inconsistent electrical switching
• Lighting control issues caused by a damaged combination switch

Installation Notes and Tips

Verify connector shape, terminal count, and vehicle equipment before installation. This switch uses a single rectangular female connector with 10 blade terminals and clip attachment. Confirm the vehicle is equipped with front fog lights and automatic high beam, and compare the original switch layout to the replacement before final assembly.

Quality Assurance

Standard Ignition subjects this switch to full testing for both mechanical action and electrical performance. The robust housing and OE-style construction are intended to meet the demands of professional service replacement work.
