Skidoo Safari How Do I Replace A Skidoo Safari Headlamp?

How do I replace a skidoo safari headlamp? - skidoo safari

I am replacing my lamp on my bike SafariScout 1990th The manual operation instrustions are incomplete. I removed the bracket and rubber boots. The following statement in the book is to "separate the bulb." I tried to run the ball the whole house, but either blocked or not is how to remove it. I tried to unscrew, but can not because the concentration fit through the slot. Help! please and thank you.
