Detailed Product Overview

What It Helps Fix

  • Headlights that do not switch between lighting modes correctly

Installation Notes and Tips

This switch uses a bolt-on attachment method and two rectangular female connectors. Verify connector shape, terminal count, and fog light configuration before installation, especially on 2008-2018 Cadillac CTS applications where fog light equipment varies by year and trim. Confirm the vehicle uses a 12-volt electrical system and match the original switch layout to the listed functions before replacement.
