Hey Hunter, thanks for reaching out. No, the Optronics LED Trailer Utility Light # BUL43CB will not work with the # A45BB flange bracket. I went out to our warehouse and grabbed both parts and tried to fit them together. The fit is very close, but the light just doesn't quite seat in the bracket the way it should.
For the # BUL43CB light you will need to use the rubber grommet # A45GB. That is the only bracket or gromet I can confirm will work with the light. If you can't use that grommet, you'll need to do a different light.
What trailer are you mounting this on?
