This kit adds an integrated red turn signal on glass to your upper mirror glass for added safety and visibility. Easily installs in minutes onto your OEM towing mirrors, with a fully plug and play wiring adapter. Replacement glass is offered with or without blind spot monitoring. Must purchase the glass according to your original mirror configuration.
**Our glass does NOT come equipped with Auto-Dim, you will lose this feature if you currently have it. We ask whether you originally had it because it dictates other fitment on the glass assembly**
Fitment includes 2019-2025 Chevy Silverado or GMC Sierra 1500, or 2020-2025 Sierra or Silverado 2500 and 3500 trucks. This product fits a variety of trucks including L5P Duramax models.

We might be biased, but we think the choice is clear. Boost is better...because of this:
it was well packaged and easy to install
Love these and pretty easy install. Install video does need an update for the 2024 trucks.
I ended up doing everything I could upgrade to my mirrors, lights, turn signal, heater, and I love how all of it came out. Great quality easy to install. Just don't make my mistake and make sure if you have auto dim mirrors that you choose the right option, they are not the same (all my fault). Like everything else I have from BA I love everything and haven't had any problems. All high quality. Would recommend to anyone. the video instructions are the best btw, so if you are not the best mechanically, you can do the install yourself.
Easy install. Secure packaging
