ETM rtr bolt on battery powered wheelie light

Didnt relize it wasnt a plug and play hopefully the light doesnt cause me to keep buying double A batteries everytome i wanna ride at night and had to modify light bracket by adding another hole i have the rtr lite. Other than that light works great plenty of wiring to reach everything

Amazing light. but where am i supposed to put the battery pack. and can i put titanium baja bolts on here?
