ACDelco Instrument Panel Dimmer Switch

The ACDelco Instrument Panel Dimmer Switch (also called a dash light dimmer switch or headlight switch dimmer control) adjusts the brightness of the instrument cluster and dash backlighting. It lets the driver set a comfortable lighting level for day and night driving.

Key Features:

• Controls instrument panel and gauge cluster illumination brightness
• Replacement part from ACDelco, the original equipment parts brand of General Motors
• Built for reliable electrical performance and long service life
• Restores smooth, consistent dimming control when the original switch is worn, erratic or failed
• Direct-replacement design for straightforward installation

A failing dimmer switch can cause flickering, dim or dead gauge lights, or lighting that will not adjust. Replacing it with an ACDelco switch brings back dependable control of dash lighting and makes the instruments easier to read at night.
