Brand new headlights and headlight brackets but still has a lot of play

[StephenCasiday]

I just bought new headlights and blinker housings and new brackets to mount them to because the ones before were missing screws and broken, but the headlight housings are still loose and wobble a lot but the blinkers and tight fitting, any fix for it?
