The prior owner had wired something in to the light circuit. I found the connections deep inside the dashboard. Once I removed it the flashing problem stopped.
It just goes to show you you need to find out everything up and put on your H-1. Something I didn't even know was there was causing the problem.

Thanks to all the help that you all gave me. And thank you to the hummerforums.com. For a platform to find the problem.
