DIY Humvee Upgrade – How to Install Rear View Mirror in HMMWV
For whatever reason, the US military chose not to include a rear view mirror in Humvees. Maybe not an issue if you are driving around Afghanistan, but a rear view mirror is definitely a “must have” item for any HMMWV that you wish to drive legally on US roads. Fortunately this is a pretty inexpensive and easy DIY upgrade that most anyone can do to their HMMWV in a few minutes.
In the video below Jeff shows how he used the following parts to add a rear view mirror to the Project Humvee Battlewagon. You can use the same parts and process to mount a rear view mirror on pretty much any vehicle.
Three ways to install a rear view mirror
Traditional: Adhesive mount to window glass
This is what you are likely most familiar with and is the way I installed the mirror in the video below.
Recommended: Screw mount
Mount to the top of the windshield frame with a screw
Easiest: Suction cup mount
I’ll share a note from one of you in the Gear Report Nation: “I went with this suction cup marine mirror (link). No issues, six months in.” -Adam

How to mount a rear view mirror with adhesive
Here are the parts required, with Amazon links:
- Permatex 81844 Professional Strength Rearview Mirror Adhesive
- CIPA 32000 10″ Day/ Night Rearview Mirror”
Honestly, after driving for a month with the mirror mounted as seen in the video wished the mirror were mounted higher.
How to screw mount a rear view mirror
The adhesive mount above held great for over a month. However, when I attempted to install a back-up camera monitor that clamps onto the rear view mirror the whole assembly broke free from the windshield. So, I opted to drill a countersunk hole in the mounting button, then used a #10 cap screw to mount to the top of the windshield frame beside the wiper motor.
As with the traditional mounting method, I used the CIPA 32000 10″ Day/ Night Rearview Mirror”
So far, this looks like a very good solution.
Suction cup rear view mirror mount
I was planning to buy one of these suction cup marine mirrors (link) when I had the idea to drill the button and install as in the above pictures. The problem was that I could only find this 4″ tall mirror with a clamp style suction cup and my back-up camera monitor won’t fit on a 4″ mirror. No directions needed here. If you can’t figure out how to clamp a suction cup to the window, then you need to hire someone to do ALL upgrades on your HMMWV.
Please leave a comment if you have suggestions on how to better install a rear view mirror in a HMMWV.
