Fit System K Source 81800 Towing Mirror F150 2004-2008

The mirrors showed up as promised and included a storage bag which is very handy. It took a little moving and pushing to get the bottom tabs to move into place but once they were in the right spot I was very confident that they would stay in place. It greatly improves the area you can see behind your truck.

Application: 2004 F150 Lariat 4x4 (new body style). My mirrors are POWER (adjustable), HEATED and have the LED turn signalsWhen I started looking for tow mirrors, I noticed some of the fit guides said they won't work with my mirror's power and heat options, but they fit perfectly; snap on and off quickly. And if you didn't know they were a snap-on mirror, you would think they are factory, especially from the front.I looked at other tow-mirror systems but none of them compared to these. They simply snap in place and seem to to fit very snug. There are no 'wedges', straps, duct-tape, super glue, welding rod or bailing wire needed to hold them in place. They do have some foam strips on the inside to keep from scratching your mirror. I also suspect the strips help keep them snug. And as nothing lasts forever, I'm sure these tow-mirrors will eventually loosen over time. Put some fresh foam strips in and you're good to goThe next biggest issue I found while shopping for tow-mirrors was the LED turn signals being covered up. Not to worry with these!For those of you that have the turn-signal LED lights like mine do, these tow-mirrors DO NOT COMPLETELY COVER those lights! In fact, it's hardly worth mentioning as they barely touch the bottom of the lights. The turn-signals can still be seen very clearly. And even if your lights were somehow covered too much, a quick trim with a Dremel or other means can cure the problem.Hope this helps,R.

I was very happy they fit perfectly

I installed this on a Lincoln MK LT pickup. Fit perfect as long as the mirror does not come in. Mine does and when I brought the mirrors in they hit the side of the truck with the innermost clip, (which you would use to remove the mirror.)I ground them off with a sander and they fit great. Secondly my mirrors have a light in the bottom of them. I drilled out a 1 and 1/2 " hole in the bottom for the light to be operatable. Easy on and easy off when not needed.

If mirrors were a bit longer would get 5 stars. Perfect fit for 2007 F150 Lariat. Very easy to use and look great!
