Looking for some options on mounting lights

Hopefully some experts, or anyone who has some experience, with mounting lights on a Yakima HD crossbar.
Shouldn’t be too difficult, but I’m not sure if there’s a product out there that I’m not seeing. I’ve searched Yakima’s website and couldn’t find anything.
The plastic center strip on the crossbar is removable and I’m able to cut it to accommodate any hardware.
Any help would be appreciated, thanks!

 

Use a square nut and then either stack some washers or get a small bushing to use as a spacer, i.e. so that the threads on the studs of your lights don't extent too far down and hit the inside of your crossbar.

Alternatively, you could use a threaded T-nut where the threads point up, and then a coupler for the studs on your lights, but that would probably add too much height to the lights IMO.

 

Thanks for the ideas!
