I have these rattly SOBs just to stay legal.
The mirrors rattle around so much at highway speeds that you really only get an idea that there are shapes to the side and rear of your Jeep. Adding a set of those blindspot dots you attached to your vents helped out big time with making it easier for me to see since the smaller reflected image does not appear to shake as much.
I wound up getting a pair of these:
They are just a set of generic Harley Davidson Long Stem mirrors (Part number 70236) on Amazon for $50.
The blind spot mirrors were HORRIBLE for backing up. I couldnt see where anything was behind me. I almost knocked my brothers jeep a time or two backing into my driveway.
These mirrors are much better. The do vibrate a very little bit, but nothing so horrible that all you can see is shapes and colors. LOL.
