I've got an XPro Templar X that I wanted a better headlight on. Seeing the following headlight, I found out it'd fit my bike from an electrics standpoint:

It just wouldn't mount to it without bungee cords, zip ties, what have you. I didn't like that as a solution. So I designed this part, which bolts together with a handful of 1/4" bolts (I believe mine were 1 1/4" long but try test fitting before you buy) and four 8mm bolts (to mount it to the bike). I recommend nylock nuts and washers to hold it together. Don't overtorque your bolts or you can crush or crack your parts.

If you're outside the US, the parts should all still work with 7mm hardware (except the four bolts to mount it to the bike, which are still 8mm).

I printed mine on a Qidi Xmax 3, but this was originally designed to fit on an Ender 3. It's tight, but if you move the parts around, all three should still fit onto an Ender 3 build plate.

For completeness' sake and so you can edit as you choose, I've included the blend file I used to make it. It's a bit of a mess, but if you export each part as just that selection, you should be able to modify and remix as you need.

Also, you're 3d printing a vehicle part made by an amateur designer - so know that you're accepting some risk.
