Headlight conversion help

So I’ve got everything hooked up and lights work fine but I am lost on where to secure this on either side. Please advise.

 

Welcome.

Self tap screw into fender well on side of battery

 

Thank you for the help. That worked great

 

Worked perfectly. Thank you for the help.

Thank you!
