With over 30+ years of painting experience, our team delivers flawless color matches, including VIN-matched factory colors, and smooth, durable finishes.
Expert hands ensure every part is prepped, painted, and cured with precision—giving you custom quality that looks straight from the factory.
· Power Function: If your truck was originally equipped with power mirrors the power function on our mirrors will work properly.
· Defrost Function: If your truck was originally equipped with rear defrost the defrost function on our mirrors will work properly.
· Signal Function: You must run the signal wires to a signal feed (harness included). All wiring internal to the mirror is done; you just need to do the truck side wiring (instructions included).
· Running Light (If Signal & Running Light or Switchback Option is Selected): You must run one wire to a running light feed (harness included). All wiring internal to the mirror is done; you just need to do the truck side wiring (instructions included).
· Rear Facing Reverse Light Function: You must run the reverse wires to the reverse wire at the rear of the vehicle. All wiring internal to the mirror is done; you just need to do the truck side wiring (instructions included).
The paint code for your truck can be found on the vehicle information sticker on the driver-side door jamb. We've attached an image depicting where the paint code is located on the sticker. The paint code will be a 3-digit code listed after “paint”. 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.
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).
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.
These will work as a reverse light after they are wired in. You must run the reverse wires to the reverse wire at the rear of the vehicle. All wiring internal to the mirror is done; you just need to do the truck-side wiring (instructions included).

No, this is included in the price and it is installed before the mirror is shipped to you.
Navigate the product page content 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 spotlight is extremely convenient!
Yes! Every electrical connector and fuse tap required for installation (seen in the video) is included with your purchase. All you need to do is install the mirrors, following our videos.
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:
Mirrors were super easy to install following the installation video. Everything works great, and my view is vastly improved over the stock Dodge mirrors
Quick shipping, easy install, and its all working great so far.
Great experience, fit perfectly look great.
everything went good. Changed the looks of my dodge.
The mirrors look and perform great! Installation was easy, wonderful video on YouTube. The lower spotter mirrors help so much over the little fisheye on the factory ones. Love the running and indicator lights as well. Definitely recommend!
