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. Also offered in a scanning sequential amber turn signal as an additional option. 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 or Scanning Amber Signal (Sequential Switchback Only)
- Running Light (No Signal): Solid White Strip Light
Running Light On & Signal Activated (Normal Switchback): Solid white light turns off during signal and amber light flashes until signal is complete. After signal is complete, white light illuminates again
- Running Light On & Signal Activated (Sequential Switchback): Solid white light turns off during signal and amber light scanning signals until signal is complete. After signal is complete, white light illuminates again
These replace the factory lights which are part numbers 23444105 and 23444106.

Packing and shipping were beyond expectations. Product was exactly as advertised and quality is amazing. Customer service is unbeatable and unlike anything I have seen before.I did order the wrong kit when I order the switchback lights but the tech support team helped me work through the issue and got the lights operating without any extra purchases and in a timely manner. I will recommend boost auto parts for their customer service alone, not to mention the great deals and products offered.
Really improved the look of the truck, nice quality, and super easy install. Took me about 40-45 minutes by simply following the video.
Great price, the install video was very very helpful. And shipping was faster than advertised. So far very pleased
