Why not just adjust the side mirrors so you don't have a blind spot?

 

Electronic blind spot monitors will be adjusted for a car, no trailer(so you will have to 100% IGNORE THEM SAYING IT US SAFE TO CHANGE LANES)....so only fix there is a better mirror...either changing the glass part, or a temp bolt on...
Trailers vary in length, and you will be slower hauling a trailer...both accelerating, slowing and lanechanges....get used too it. Get used to waiting for a big open space....
Going fast with a trailer is a disasters in the making....

 

I've posted too many times about this being the most common mistake made by automobile drivers. Do a little bit of search and find out how to properly adjust your mirrors and you won't have any blind spots.

 

Or you could go with curb feelers, AKA park-assist 1.0.

 

It's cheaper to mount two seeing eye dogs to the blind spots on the rear bumper. :lol:

 

and a headcheck...turning your head too look...guessing aftermarket sensors might be mounted on the mirrors for easy install, but my feeling is, unless they came on the car, bolting them on will result in a cluge job that may/maynot work and be trustworthy.

 

I didn't have to install them, they are standard equipment on our new XF. They are a bit odd to get used to at first, however I can see there's going to be benefit 10-fold down the road as our eyesight and perception continue to diminish. Not that I'm unaware of my surroundings mind you, I do know when I can talk on my cell phone and when I cant... so far. Seriously though, they're cool and I think we're gonna like the feature.

 

Really.......top up or down has nothing to do with blind spots.
Proper side view mirror adjustment is what is needed.
