How do people mount their flat surface lights to the aux light bracket?

Got the MaMo brackets for aux lights up front. I want to put Rigid D2's on, but the mount is for a flat surface as many lights are. So, wondering how people are solving this problem. It's got to be a bar mount with flat surface to mate the base of the light to. Looking for suggestions. Some of the bar brackets that would seem to work get fairly bad reviews where not moving on the bar is concerned. Thanks

I have used some PIAA mounts on tubular bars. Fairly small flat point however at light mount point, though the pictured one here is larger

When I bought my bike, the previous owner had a mounting bracket under the oil cooler where the PIAAs were mounted. That location with that bike often had the lights hitting the front fender. I removed the Roundels and attached the lights there, as seen in the picture below. The wide separation makes for a larger triangle. Since I took this photo, I have since added an additional (but smaller) Roundel on the side panels.

My K has PIAA knockoffs and I mounted them with no problems on the side panels as well.

On another note, I have since removed the PIAA's light bulbs and replaced them with $12 LEDs from Home Depot. Ran for awhile with one LED and the standard PIAA; no difference with the light output, but less power is being used.
