I placed them just on the inside of the warning lights.Do you have them in towards the window or out? If out, can you still see the warning lights on the mirror?
I did that and still have them adjusted that way. But it is still quicker for me to look in my little round add-on's to determine whether anyone's there.you can angle the side mirrors so you dont have a blind spot. I do this on every one of my cars I've ever had. Adjust the side mirrors just past the side of the truck (so you can't see the truck anymore). When a car passes you and it leaves your mirror, you'll see it over your shoulder so there's no more blind spot.
