Absolutely! These lights are designed to fit perfectly into OEM & Boost Auto mirrors, but will fit into ALL Sierra and Silverado 2015 style tow mirrors on the market.

If you just have the running lights on the light will be a solid white strip. If you activate the turn signal while the running lights are on the white light will turn off, and the amber light will flash. After the signal turns off the white light will turn back on.

If your running lights are off the amber signal light will flash like a normal signal.

The price is for a SET of lights (one left, one right), and the required wiring harness to connect to the truck.

These are exclusively offered by Boost Auto Parts (we designed and developed the tooling), so we do not offer the lights individually because they will not match any other lights on the market.

Absolutely! We offer the lights by themselves (which is what you're viewing right now), or already installed in Boost Auto tow mirrors.

If you want to purchase mirrors with switchback reflectors already installed please select your year make and model on our homepage and you will be directed to the tow mirror product page.

These are Boost Auto Parts brand switchback reflector lights. These are 100% designed by Boost Auto Parts and are manufactured and sealed using OEM equipment and techniques.

These are NOT marker lights that are cut open and retrofitted with other companies products. These are OEM quality lights that are professionally sealed and built to last.

Installation time varies depending on the current function of your front light. Our installation videos and custom wiring harnesses make the process easy, and our support staff is available for any questions that come up. The below information can be used as a rough guideline:

-Currently Signal Only: 1-2 Hours

-Currently Running Light Only OR Running Light & Signal: 1 Hour or Less

The smoked lens is a dark smoked lens with a black plastic backing behind it.

The clear lens is a clear lens with a chrome plastic backing behind it.

Absolutely. All of our products come standard with our 1-year warranty.

Absolutely, & install is very easy on 2015+ OEM mirrors that are already properly functioning (running light only on the front, signal only on the glass).

Installation into OEM mirrors is typically 20 minutes per side and requires no cutting, crimping, or soldering.

Sorry, we do not offer paint services. Most body shops will do this for less than $100 though.

No, the required harnesses are included with the switchbacks.

First and foremost, these switchbacks are not marker lights that are cut open and retrofitted with strips. These were designed with full intent of operating as switchbacks and are manufactured on an OEM assembly line.

Retrofitted lights often have fitment issues due to excess glue since the lights originally needed to be split open. These lights are sealed with automated equipment and tight tolerances, therefore fitment issues are non-existent.

These lights use 100% OEM sealed connectors, so moisture will never enter around the connector (retrofitters must silicone around the connector to try and keep moisture out). These also feature a semi-permeable membrane (the OEM GM lights don't even have this), so if moisture were to ever get in it has a path out (whereas the competition is 100% sealed, so the moisture will stay).

The other switchback lights on the market just come with three loose wires, and it is up to you to splice on extensions and run wires to the correct functions. Included in the price when you checkout is a custom harness specific to your exact setup to ensure a hassle free install. All wires that you will need are included in the package.

The competition requires mounting of external switchback modules inside the mirror to control the lights. Our modules are internal to the lights, so no modules need to be mounted anywhere.

What is the main takeaway? These are not retrofitted switchbacks. These are OEM quality lights where no corners have been cut.

Our exclusive Start-Up Sequence is a unique light function that activates anytime the parking lights of your truck are initially turned on. We've included a dynamic image depicting the Start-Up Sequence on our lights.

Please note, the Start-Up Sequence is currently only offered on Smoked Lights
