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.

Item was easy to install for our customer. We have not gotten any calls for issues, so the customer must be happy!!
Way better than the ugly stock units. Easy to install, overall very happy.
Hello, the lights didn’t work on my truck. The plug didn’t math with the outlet of the truck. I have a 2019 Chevrolet duramax 2500HD. What i can I do ? Do I return them to get the right ones ? Or am I doing something wrong ?
Hi Miguel, These should work without an issue on a 2019 Duramax. Reach out to our team at firstname.lastname@example.org so we can get this resolved ASAP. Thanks, -The Boost Auto Team
Easy install but you may need harness upgrade for full function (if you are installing tow mirrors for the first time). I have a 2014 silverado LTZ with full function mirrors (tilt, memory, heat, reverse, puddles , and signals.). Without the harness upgrade I do not have full-time running lights or cargo lamps. These look sharp!! Go for the sequential option
It was great. Easy replacement/installation, and the accompanying video answered any questions.
