I'm planning on getting this light and doing the same mounting, however my concern is someone getting there with an Allen wrench. I live close to LA. Would you know if there is a way to secure this light?
Unfortunately, I do not know of a way. I have heard the guys will tac weld the bolt but that'll mean you'll be grinding the head off if you need to remove it. Also I believe you can buy a "locking" nut online but I'm unsure of who sells them..
