These are drop in replacement switchback marker lights for the 2015 new style GM tow mirrors fitting Silverado and Sierra. These will illuminate as a white LED strip during running light mode, and flash as an amber LED strip during signal mode. They are offered with a smoked or clear lens, and the included wiring harness makes installation easy (links to videos are below).
These lights operate as follows:
- Signal (No Running Light): Flashing Amber Signal
- Running Light (No Signal): Solid White Strip Light
-
Running Light On & Signal Activated: Solid white light turns off during signal and amber light flashes until signal is complete. After signal is complete, white light illuminates again
These replace the factory lights which are part numbers 23444105 and 23444106.
