Great lights
I’ve never understood why Can-Am just didn’t include these to begin with. These are great lights and fairly easy to install.

These were a breeze to install and they look great. The outside bolt is hard to get tight because of its location, you have to put the nut in first then screw the bolt into it or it won't tighten properly. It also helps to cut the length of the bolt, no need for such a long bolt in that small of space. WATCH THE VIDEOS!!! These don't come with instructions.

Check ALL Parts
The lights worked as advertised. Check ALL wire harnesses. The connector for the right fender did not have the plug cover for the hookup. I made it work. The left fender was complete. It was easy to install with the instructions. The set adds additional attention when turning and while running. Would have loved to give it a 5.

Fog Light Install
Installed on 2020 Spyder F3-T. Not as easy as the video shows. Screw holes either had too much paint or not tapped to match the screws as mentioned in other's posts. Washers are not sized properly for the application as on two of the bolts the washers wouldn't fit. Fortunately I had a couple that would fit, but for the price you shouldn't have to "jimmy rig" anything. I used painter's tape on my garage door to adjust the beams before putting all of the panels back on. I installed these along with the new LED headlights since I was going to have it stripped apart. The switch hole was too small, but I used a reamer to open it up a little, again, shouldn't have to modify something at this price. Total install took over four hours for fog/running lights and headlights (no instructions for my bike). Install took too long due to lack of any instructions, but the end results are great.

Good and Bad
First off, the lights themselves are super looking and bright. Love the look.
As a few others have mentioned, the instructions are a little off (at least for my 2019 F3 Ltd). The outside bolt passes through where a washer cannot be used.
Also, the screws provided to mount the light to the U-bracket are very very difficult to turn into the holes on the lights. So difficult in fact I was unable to fully tighten all of them.
There is also no mention of what to do with the large "box" on the wiring harness? How to secure it from rattling around.
The switch has to be turned (screwed) into the round hole where is sits but does fit (others mentioned it did not fit at all).
Lastly-during installation, you need to leave the lights and brackets loose until you line everything up with the holes in your faring.....
