PLEASE continue in your ORIGINAL topic on this subject. You now have 5 topics all related to that one. Your original topic mentioned the light and we asked you to get it scanned. Post this information in that topic.

Multiple posts on the same topic get very frustrating, confusing, and make a mess of our database.
