I use a three inch and I prefer it to be outside low. That's how my Jeep is set up on both sides. I find a two inch is too small, especially when driving at night.

 

2 inch high and outside.

 

3 inch - outside low

 

Always on the bottom and on the outside of the mirror. If I use the rectangular one like in the picture, I also flip the thick side in, this gives me the widest blind spot picture. This benefits you both driving and sitting in your rig. No one can walk up on you either! Same position if you're using a round mirror.

 

First thing I add to every vehicle (if they don't have them). I prefer the "rectangle" shaped ones and put it low outside and as other poster said, thick side toward vehicle.

 

2 inch outside low is where I put mine.

 

I need to get a blind spot mirror for mine also. This is definitely one area when I really wish I had my Ford F-350 mirrors. I also wish I could wedge my F-350's 6.7l turbo diesel into the Jeep, but then again I'd just be driving an engine.............

 

Have a 2" round that rotates to get the right field of view. Mounted high and outside.

 

I went 2" outside low. Thinking of switching to the rectangular ones though. Objects in the 2" are tiny. How did Chrysler manage to make such large mirrors so useless! I nearly wiped out two motorcyclists in my first week of ownership.

I thought it must be me only who wondered this. The mirrors seem pretty big but not very good, I don't know how that works.

 

You don't need blind spot mirrors. If you adjust your mirrors properly, you won't have any blind spots. This is true for most cars that have the range of necessary adjustment built into the design.

What they taught me, and most everyone else, in drivers ed back in 1970 is wrong. When my son was learning to drive in Michigan, his teacher had the parents attend one day and they explained proper adjustment. Most of us are used to seeing a little corner of the Jeep (or car) in the mirror at all times. The side mirrors need to be pushed out much further than that. When done properly you can't see your own vehicle in the mirrors under normal circumstances.

When done properly, cars in your rear view mirror will transition to a side mirror just as they leave the vision of the rear. As they progress further up the side as they pass you, you will pick them up in your peripheral vision as you lose them in the side mirror.

It's fantastic, but it takes a week or so to get used to it because you can't see you own vehicle in the mirror. When driving...if you don't see a car in your side mirror...that means there isn't one.

You sort of adjust them in the same manner as before (leaving a corner of your vehicle in view in the mirror)...with one big exception. Don't sit upright while making the adjustment. Put your head against the driver's window while adjusting. You'll find that to get the desired result, you'll have to move them much further out...in fact, the jeep is at the limit of its movement. For the passenger side, lean as far in to the center as you can while adjusting.

This isn't just me...the SAE has done studies and this is what they recommend. I couldn't drive any other way now.

I'm going to have respectfully disagree! You are correct in that if your mirrors are set up correctly you shouldn't see your own vehicle. To say you don't "need" them is technically correct BUT they provide a HUGE advantage in heavy traffic. There's a reason that manufacturers include them on all vehicles that are typically bought to tow. There's a reason that all semis come with them, often multiple blind spot mirrors. There's also a reason that school buses come from the factory with them. The reason is that they provide an advantage to the driver. That article was written in February 2010, a lot has changed on our roads and with our vehicles. Even our vehicles monitor our blind spots, so yes you do need something to help with blind spots. If you don't want one on your vehicle that's up to you. Personally, all of my vehicles that didn't come with one from the factory will get one.

 

Having driven plenty of vehicles where you can't use the inside rearview mirror (or in the case of "big trucks" - I am a CDL driver - you don't have one) you can't rely on it. For most the point of having the outside mirrors adjusted so you can see a corner of your vehicle is to give a sense of depth to the image. The picture is with the camera a little too far out so more of the back corner is showing than what I normally see sitting proper in the seat.

To reduce blind spots I've found the best way is with a spot mirror, 3 in, mounted low and outside. The other benefit to this is that you can see your rear tires. Invaluable when negotiating obstacles, even if it's the curb in a parking lot.

 

Can anyone post a link (Amazon or other) for a blind spot mirror that’s a perfect fit for the contours of the JK mirror?

 

I use these on both sides, but they are large, they actually replace 80% or more of the mirror. I mounted them to the top and they fit all the way across almost side to side. There's about an inch exposed on the bottom of the old mirror.

Since they are so large though, the distortion isn't as bad as the little ones. I can see down the side of my Jeep and all the way to 90 degrees out from the rear driver's door, there are no blind spots at all, if it's not in the mirror it's directly out of my window. I had used mirrors like this forever so I'm used to them, I know how the location on the mirror relates to real life.

The one's I buy are from O'Reilly's though - they are real glass mirrors too. The listing below is how they look but the review said these were plastic and I won't but plastic because they scratch and haze and yellow..
