Gig light

So, I am needing 3 mounts as shown in this pic ffor my gig lights…about 4" long and 2" wide…any idea where I can find mounts like this?

Buy some aluminum flat bar from Lowes and make them.

Yamaha 250

Try an auto parts store. Looks like the same type light brkt that I’ve seen used on jeeps
