Expert hands ensure every part is prepped, painted, and cured with precision—giving you custom quality that looks straight from the factory.
Check out the dynamic pictures found on the product page content for an idea of how the lights will function.
Signal Only: The lights will only flash with signal. They will not illuminate as running light.
Signal & Running Light 1.0: The lights will flash as a turn signal. At night when the running lights are activated, the lights will operate at 50% intensity for running light, 100% intensity for turn signal.
Signal & Running Light 2.0: The lights will flash as a turn signal. At night when the running lights are activated, the lights will operate at 100% intensity for running light, 100% intensity for turn signal.
Switchback: The lights will flash as an amber turn signal during the day. At night when the running lights are activated, the lights will operate at 100% intensity in WHITE for running light. When the turn signal is activated, the lights will operate at 100% intensity in AMBER in a flashing pattern until the turn signal is de-activated (at which point it will return to a solid white light).
We use the OEM connector to unlock the plug and play features on your Colorado or Canyon.
Power Feature: All vehicles that originally came with power adjust mirrors will plug and play for this feature. Please note memory, seat recall, and curbview assist are not supported.
Defrost Feature: All vehicles that originally came with rear window defrost will be plug and play for defrost. Even if your original mirrors didn't have defrost, the heat function will work on ours if you had rear window defrost!
Lighting Features: All lights need to be wired into the vehicle. We offer an easy to follow video showing how to wire it and include all the wire you will need.
The paint code for your truck can be found on the service parts identification sticker in the glove box. We've attached an image depicting where the paint code is located on the sticker. The paint code can be found at location 16. If you're unsure of your paint code, simply type your vehicle's color.
We use your vehicle's VIN and paint code to match exactly the factory color it came with. We do not offer an option to paint these in a different color than what the truck was equipped with from the factory.
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 offered on all light functions except Signal Only or Sequential Signal Only.
Smoked Dotted (Amber LED)- Amber at all times
Amber Dotted (Amber LED)- Amber at all times
Smoked Strip- Amber if signal only or signal & running light, color changing (white running light, amber signal) if switchback
Clear Strip- Amber if signal only or signal & running light, color changing (white running light, amber signal) if switchback
Scroll up to see the difference; it's night and day! If you have tint on your truck the high output spot light will make the world of difference.
Even if you don't have tint, the high output spot light is extremely convenient!
Yes, these mirrors can be extended to a length 3" beyond the retracted state.
Typical installation for these mirrors (including wiring in all of the lights) is approximately 2-4 hours depending on the skill level of the person performing the installation. We provide a YouTube video detailing the tap locations, and provide all of the fuse taps.
The base which mounts to the door is made of a durable metal with a smooth black finish, and the plastics are ABS with a black textured finish.
This all depends on personal preference. Please check the pictures we have online to see how they will look.
All mirrors are backed by our standard 1-year warranty.
The upper glass is a flat piece of glass which will have a magnification effect, whereas the lower glass is convex so objects will appear further than they actually are (this is the OEM design).
Unfortunately, the design of the door panels on the Colorado & Canyon arch up towards the front of the vehicle, so depending on the height of the driver the lower convex glass may be partially restricted in the retracted state due to the door panel blocking it. This would be the case on ALL tow mirrors for the Colorado and Canyon because of the design of the door panel. In the extended (towing) position, both pieces of glass should be fully visible.
The build date is found on the corner of the VIN sticker located in the driver's door jamb.
This is only relevant if you have a 2017, if you have any other year DISREGARD this.
We've included a graphic below depicting the difference in brightness between Low Output Flood Lights and High Output Spotlights
We might be biased, but we think the choice is clear. Boost is better...because of this:
I expected good quality, but this is beyond my expectations.
They look phenomenal, really make the truck stand out
Mirrors went on without any issues. Youtube videos were very helpful. Quality of the product is superb and the design works great for my 2021 GMC Canyon AT4 Crew Cab!
Great! The mirrors look awesome on my Colorado! Makes such a big difference in the look I was going for. And the mirrors are of great quality.
