Blind Spot Mirror Placement

Blind spot mirrors may be placed anywhere you wish, but they are typically located on the bottom outside corner of a vehicle's side-view mirror. The desired placement varies from one person to the next.


You can try out different placements by putting a piece of folded tape on the back of the blind spot mirror and sticking it onto your side-view mirror where you think you might want it. Then sit in your car or truck and check to see if the mirror is reflecting the area you'd like to see. Keep adjusting the placement until it suits your needs.


When you have the mirror where you want it, peel off the backing and stick it on permanently.

Video Transcript for K-Source Blind Spot Mirror Feature Review

Hi there, haulers. Today, we're going to be taking a look at K-Source's Wedge Style, Convex Blind Spot Mirror. Before we show off our mirrors, we're going to go ahead and get a baseline with our truck here that has factory blind spot mirrors on them. It's got that lower convex mirror there that's going to be similar to the blind spot convex mirrors that we're going to be adding to our older truck over there. Here, I can clearly be seen in our factory mirror, both the straight one on top, as well as our blind spot down on bottom that has the convex mirror. But as I take a step towards the outside, I'm no longer visible in our regular mirror, but I can still be seen in our lower blind spot mirror due to that convex shape.Now that you've seen what our factory mirrors look like, we're going to go ahead and install one of our blind spot mirrors on our older truck, and you're going to be able to compare, to see that with these little mirrors, you're going to get the same functionality.

Now we're going to take a look at our blind spot mirror. You can see here that we can see our trailer in our factory mirror, but we get a much more complete view of the trailer in our blind spot mirror, increasing our viewing angle. I also really like it for backing up, if I've got to get into any tight spots where I really need to get the trailer angled really hard because, in our factory mirror, I lose sight of the back of my trailer, but I can still see it in the blind spot here.As you can see here, I was able to easily and confidently get my trailer parked into a nice tight spot here right next to our truck. You really couldn't have gotten any closer than this without a nice mirror to help you guide yourself in. I've also found them quite useful when hauling a 30 or 40-foot camper.

It's great for your RV's as well. They're extremely long to increase your viewing angle there. I also find it great for your regular vehicles that just have some blind spots that really bother you. You can throw those in and eliminate those blind spots.Unlike our factory mirror, which is a flat surface, our retro mirror here is a convex shape, which gives you a wider viewing angle. You do want to keep in mind that in a convex mirror, objects may be closer than they appear.

This is the retro model. It has that retro look. So, if you are looking for something on an older vehicle and you want to maintain that retro aesthetic, this can be a great option for you. But in my personal opinion, I would go for K-Source's Round 360-Degree Adjustable Convex Mirror because you just get a much better viewing angle. Another reason I like those, is once you stick this on, it's set for the driver and the position that they're in.

But with the adjustable one, you could easily have another driver swap out with you if you're on a long road trip and they can adjust that mirror for how they like to sit in the vehicle.The increased viewing angle of our convex mirror here is going to be great for changing lanes and passing other vehicles. It measures 1-1/2 by 2-1/4" for a nice small little mirror that can easily be attached to your factory mirror without obstructing too much of its viewing angles. Now, before you pull off the backing and stick it onto your mirror, I highly recommend you just hold it up there, maybe get an assistant to help hold it up in a place while you sit at your normal sitting angle in your vehicle so you can find the best angle because you can rotate them and put them in all the different ways that works best for you.They're extremely easy to install. I highly recommend that you clean your mirror to ensure that you get good adhesion to it. On back, they have an adhesive pad, and you'll just want to peel off the adhesive backing, and then we can go stick it in place. That completes our look at K-Source's Wedge Style Convex Blind Spot Mirror.

The K-Source 3" Round Blind Spot Adjustable Convex Mirrors add a high degree of comforting safety for the driver while in traffic.

I stuck them in the lower outside corner of both outside rearview mirrors on my Toyota Sequoia. I then simply pushed to adjust them to where I can see the entire other car in the adjacent traffic lane (on either side of my car) all the way up to where the other car's front bumper is next to my front door!

Now, THAT's a convex mirror that does the job well!

Although I always look before changing lanes (duh!), I know exactly what I am going to see in advance. This makes driving in traffic MUCH safer for everyone and easier on the nerves.

An added benefit -- convex mirrors make backing into a parking space a breeze. You can see the painted stripes of the parking space on the bottom of both convex mirrors. Do the higher math and create the same space between each stripe and your vehicle, put'er in reverse and simply stop before kissing the concrete wall! What could be easier? Well, going in straight would be easier, but then you have the hazard of backing out into the parking lot kamikazes. Go ahead, learn a new skill set, back in next time with confidence using your new convex mirrors.

I have used convex mirrors for many years and the K-Source Mirrors are perfect...simply peal and stick and watch your visual awareness on the road improve dramatically. You will kick yourself for not having used them before!

Great product!

These stick on mirrors are great very useful and still look like brand new for a year old.. They adjust perfectly for that blind spot.
by:
Big improvement over the 3 inch round ones.
by:
Useful on a caged tractor application. Easy to keep track of pulled implements. Replaced the 1 inch square adhesive tab with a full size 2 inch 3M double stick pad. No wobble and clear view to the rear.
by:
The product I had been looking for and a sales and delivery process that was easy! Thank you!
by:
I mostly want to thank etrailer for helping me with a mistake I made on the order. They made it easy for me to correct my mistaken order and get the correct size mirrors. The K-Source mirrors are the best I have found; the way they adjust is so much more functional than every other blind spot mirror I have tried - and I have tried a lot of them.
by:
I searched for "non-adjusting" blind spot mirrors to replace a set of wobbly adjustable ones I had bought. These are just perfect for me. Glad I found these. The ordering process was easy, shipping was fast, and I am a very pleased customer.

  • How to Place K-Source Blind Spot Mirror
    Hi Gary; the K-Source Blind Spot Mirror # KSCW022 is typically installed on the bottom outside corner with the thinner part closer to the vehicle as seen in the video. However, you can place it in any position/direction that works best for you. There really is no right or wrong here as long as it allows you to see your blind spot. Since everyone is different, and sits in a different position in their vehicle, we recommend using a piece of folded tape on the back and moving it around to...
