Adjusting Front Turn Signal And Headlight Horizontal?

Hi - I’m new. Thanks for having me. .

I can’t seem to find this exact information. I am hoping someone can help me. I have a 2013 Bonneville SE. At the end of last season, my bike dumped over in the driveway. I didn’t notice at the time that the brackets that hold the headlight and turn signals had shifted over to the left. So the headlight is no longer centered, and the front turn signals are also not centered. Does anyone know where I can find the information on adjusting these back to where they need to go? I can post pics if needed.
