Been wrestling with this question. Of course I believe in the need for a weapon mounted light for home defense but what about my "truck" gun. I know I am within my rights on my own property but what do I run into if I use a weapons mounted light to light an area like a parking lot in a self defense situation? Maybe I should use a handheld in addition to the WML? Maybe not an issue? I don't know. Seems like a WML and a handheld is a little redundant. Not sure what Indiana law says about this?
